3. General Questions
Q: I want to use IPv6 locally but I don't have a external IPv6 connection.
External lookups are slow.
A: You can use server clauses to stop named making external lookups over
IPv6.
server fd81:ec6c:bd62::/48 { bogus no; }; // site ULA prefix
server ::/0 { bogus yes; };
3. Operations Questions
Q: How to change the nameservers for a zone?
A: Step 1: Ensure all nameservers, new and old, are serving the same zone
content.
Step 2: Work out the maximum TTL of the NS RRset in the parent and
child zones. This is the time it will take caches to be clear of a
particular version of the NS RRset. If you are just removing
nameservers you can skip to Step 6.
Step 3: Add new nameservers to the NS RRset for the zone and wait until
all the servers for the zone are answering with this new NS RRset.
Step 4: Inform the parent zone of the new NS RRset then wait for all
the parent servers to be answering with the new NS RRset.
Step 5: Wait for cache to be clear of the old NS RRset. See Step 2 for
how long. If you are just adding nameservers you are done.
Step 6: Remove any old nameservers from the zones NS RRset and wait for
all the servers for the zone to be serving the new NS RRset.
Step 7: Inform the parent zone of the new NS RRset then wait for all
the parent servers to be answering with the new NS RRset.
Step 8: Wait for cache to be clear of the old NS RRset. See Step 2 for
how long.
Step 9: Turn off the old nameservers or remove the zone entry from the
configuration of the old nameservers.
Step 10: Increment the serial number and wait for the change to be
visible in all nameservers for the zone. This ensures that zone
transfers are still working after the old servers are decommissioned.
Note: the above procedure is designed to be transparent to dns clients.
Decommissioning the old servers too early will result in some clients
not being able to look up answers in the zone.
Note: while it is possible to run the addition and removal stages
together it is not recommended.

4. Operating-System Specific Questions
Q: Why do queries for NSEC3 records fail to return the NSEC3 record?
4.1. HPUX
A: NSEC3 records are strictly meta data and can only be returned in the
authority section. This is done so that signing the zone using NSEC3
records does not bring names into existance that do not exist in the
unsigned version of the zone.

Q: Why does named lock up when it attempts to connect over IPSEC tunnels?

<para>
Then start the relevant service:
</para>
<informalexample>
<programlisting>
% sudo service org.isc.named start</programlisting>
</informalexample>
<para>
Named will look for /etc/rndc.key when it starts if it
doesn't have a controls section or the existing controls are
missing keys sub-clauses. This is persistent upon a
reboot, so you will have to do it only once.

This option should be unnecessary for the vast majority of users. The use of this option could even be harmful because the specified value may exceed the limitation of the underlying system API. It is therefore set only when the default configuration causes exhaustion of file descriptors and the operational environment is known to support the specified number of sockets. Note also that the actual maximum number is normally a little fewer than the specified value because

It is therefore set only when the default configuration
causes exhaustion of file descriptors and the

Note also that the actual maximum number is normally a little

If <command>use-v4-udp-ports</command> or
<command>use-v6-udp-ports</command> is unspecified,
<command>named</command> will check if the operating
system provides a programming interface to retrieve the
system's default range for ephemeral ports.
If such an interface is available,
<command>named</command> will use the corresponding system
default range; otherwise, it will use its own defaults:
</para>

use-v6-udp-ports { range 1024 65535; };
</programlisting>
<para>
Note: make sure the ranges be sufficiently large for
security. A desirable size depends on various parameters,
but we generally recommend it contain at least 16384 ports
(14 bits of entropy).
Note also that the system's default range when used may be
too small for this purpose, and that the range may even be
changed while <command>named</command> is running; the new
range will automatically be applied when <command>named</command>
is reloaded.
It is encouraged to
configure <command>use-v4-udp-ports</command> and
<command>use-v6-udp-ports</command> explicitly so that the
ranges are sufficiently large and are reasonably
independent from the ranges used by other applications.
</para>
<para>
Note: the operational configuration
where <command>named</command> runs may prohibit the use
of some ports. For example, UNIX systems will not allow
<command>named</command> running without a root privilege
to use ports less than 1024.
If such ports are included in the specified (or detected)
set of query ports, the corresponding query attempts will
fail, resulting in resolution failures or delay.
It is therefore important to configure the set of ports
that can be safely used in the expected operational environment.

If <span><strong class="command">port</strong></span> is <span><strong class="command">*</strong></span> or is omitted,

It is generally strongly discouraged to
specify a particular port for the

options; it implicitly disables the use of randomized port numbers
and leads to insecure operation.
The <span><strong class="command">avoid-v4-udp-ports</strong></span>
and <span><strong class="command">avoid-v6-udp-ports</strong></span> options can be used
to prevent named
from selecting certain ports. The defaults are:
a random port number from a pre-configured
range is picked up and will be used for each query.
The port range(s) is that specified in
the <span><strong class="command">use-v4-udp-ports</strong></span> (for IPv4)
and <span><strong class="command">use-v6-udp-ports</strong></span> (for IPv6)
options, excluding the ranges specified in
the <span><strong class="command">avoid-v4-udp-ports</strong></span>
and <span><strong class="command">avoid-v6-udp-ports</strong></span> options, respectively.
</p>
<p>
The defaults of the <span><strong class="command">query-source</strong></span> and

are:
</p>

If <span><strong class="command">use-v4-udp-ports</strong></span> or
<span><strong class="command">use-v6-udp-ports</strong></span> is unspecified,
<span><strong class="command">named</strong></span> will check if the operating
system provides a programming interface to retrieve the
system's default range for ephemeral ports.
If such an interface is available,
<span><strong class="command">named</strong></span> will use the corresponding system
default range; otherwise, it will use its own defaults:
</p>
<pre class="programlisting">use-v4-udp-ports { range 1024 65535; };
use-v6-udp-ports { range 1024 65535; };
</pre>
<p>
Note: make sure the ranges be sufficiently large for
security. A desirable size depends on various parameters,
but we generally recommend it contain at least 16384 ports
(14 bits of entropy).
Note also that the system's default range when used may be
too small for this purpose, and that the range may even be
changed while <span><strong class="command">named</strong></span> is running; the new
range will automatically be applied when <span><strong class="command">named</strong></span>
is reloaded.
It is encouraged to
configure <span><strong class="command">use-v4-udp-ports</strong></span> and
<span><strong class="command">use-v6-udp-ports</strong></span> explicitly so that the
ranges are sufficiently large and are reasonably
independent from the ranges used by other applications.
</p>
<p>
Note: the operational configuration
where <span><strong class="command">named</strong></span> runs may prohibit the use
of some ports. For example, UNIX systems will not allow
<span><strong class="command">named</strong></span> running without a root privilege
to use ports less than 1024.
If such ports are included in the specified (or detected)
set of query ports, the corresponding query attempts will
fail, resulting in resolution failures or delay.
It is therefore important to configure the set of ports
that can be safely used in the expected operational environment.

This option should be unnecessary for the vast majority
of users.
The use of this option could even be harmful because the
specified value may exceed the limitation of the
underlying system API.
It is therefore set only when the default configuration
causes exhaustion of file descriptors and the
operational environment is known to support the
specified number of sockets.
Note also that the actual maximum number is normally a little
fewer than the specified value because

BIND 9.4 onwards implements "allow-query-cache". The "allow-query"
option is no longer used to specify access to the cache. The
"allow-query" option continues to specify which hosts are allowed
to ask ordinary DNS questions. The new "allow-query-cache" option
is used to specify which hosts are allowed to get answers from the

"allow-recursion" is used if it is set, otherwise "allow-query" is

A DNS Resource Record (RR) for Encoding
Dynamic Host Configuration Protocol (DHCP) Information (DHCID RR)
Status of This Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.

Abstract
It is possible for Dynamic Host Configuration Protocol (DHCP) clients
to attempt to update the same DNS Fully Qualified Domain Name (FQDN)
or to update a DNS FQDN that has been added to the DNS for another
purpose as they obtain DHCP leases. Whether the DHCP server or the
clients themselves perform the DNS updates, conflicts can arise. To
resolve such conflicts, RFC 4703 proposes storing client identifiers
in the DNS to unambiguously associate domain names with the DHCP
clients to which they refer. This memo defines a distinct Resource
Record (RR) type for this purpose for use by DHCP clients and
servers: the "DHCID" RR.

RFC 4701 The DHCID RR October 2006
1. Introduction
A set of procedures to allow DHCP [7] [11] clients and servers to
automatically update the DNS ([3], [4]) is proposed in [1].
Conflicts can arise if multiple DHCP clients wish to use the same DNS
name or a DHCP client attempts to use a name added for another
purpose. To resolve such conflicts, [1] proposes storing client
identifiers in the DNS to unambiguously associate domain names with
the DHCP clients using them. In the interest of clarity, it is
preferable for this DHCP information to use a distinct RR type. This
memo defines a distinct RR for this purpose for use by DHCP clients
or servers: the "DHCID" RR.
In order to obscure potentially sensitive client identifying
information, the data stored is the result of a one-way SHA-256 hash
computation. The hash includes information from the DHCP client's
message as well as the domain name itself, so that the data stored in
the DHCID RR will be dependent on both the client identification used
in the DHCP protocol interaction and the domain name. This means
that the DHCID RDATA will vary if a single client is associated over
time with more than one name. This makes it difficult to 'track' a
client as it is associated with various domain names.
2. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [2].
3. The DHCID RR
The DHCID RR is defined with mnemonic DHCID and type code 49. The
DHCID RR is only defined in the IN class. DHCID RRs cause no
additional section processing.
3.1. DHCID RDATA Format
The RDATA section of a DHCID RR in transmission contains RDLENGTH
octets of binary data. The format of this data and its
interpretation by DHCP servers and clients are described below.
DNS software should consider the RDATA section to be opaque. DHCP
clients or servers use the DHCID RR to associate a DHCP client's
identity with a DNS name, so that multiple DHCP clients and servers
may deterministically perform dynamic DNS updates to the same zone.
From the updater's perspective, the DHCID resource record RDATA
consists of a 2-octet identifier type, in network byte order,
Stapp, et al. Standards Track [Page 3]
RFC 4701 The DHCID RR October 2006
followed by a 1-octet digest type, followed by one or more octets
representing the actual identifier:
< 2 octets > Identifier type code
< 1 octet > Digest type code
< n octets > Digest (length depends on digest type)
3.2. DHCID Presentation Format
In DNS master files, the RDATA is represented as a single block in
base-64 encoding identical to that used for representing binary data
in [8], Section 3. The data may be divided up into any number of
white-space-separated substrings, down to single base-64 digits,
which are concatenated to form the complete RDATA. These substrings
can span lines using the standard parentheses.
3.3. The DHCID RR Identifier Type Codes
The DHCID RR Identifier Type Code specifies what data from the DHCP
client's request was used as input into the hash function. The
identifier type codes are defined in a registry maintained by IANA,
as specified in Section 7. The initial list of assigned values for
the identifier type code and that type's identifier is:
+------------------+------------------------------------------------+
| Identifier Type | Identifier |
| Code | |
+------------------+------------------------------------------------+
| 0x0000 | The 1-octet 'htype' followed by 'hlen' octets |
| | of 'chaddr' from a DHCPv4 client's DHCPREQUEST |
| | [7]. |
| 0x0001 | The data octets (i.e., the Type and |
| | Client-Identifier fields) from a DHCPv4 |
| | client's Client Identifier option [10]. |
| 0x0002 | The client's DUID (i.e., the data octets of a |
| | DHCPv6 client's Client Identifier option [11] |
| | or the DUID field from a DHCPv4 client's |
| | Client Identifier option [6]). |
| 0x0003 - 0xfffe | Undefined; available to be assigned by IANA. |
| 0xffff | Undefined; RESERVED. |
+------------------+------------------------------------------------+
3.4. The DHCID RR Digest Type Code
The DHCID RR Digest Type Code is an identifier for the digest
algorithm used. The digest is calculated over an identifier and the
canonical FQDN as described in the next section.
Stapp, et al. Standards Track [Page 4]
RFC 4701 The DHCID RR October 2006
The digest type codes are defined in a registry maintained by IANA,
as specified in Section 7. The initial list of assigned values for
the digest type codes is: value 0 is reserved, and value 1 is
SHA-256. Reserving other types requires IETF standards action.
Defining new values will also require IETF standards action to
document how DNS updaters are to deal with multiple digest types.
3.5. Computation of the RDATA
The DHCID RDATA is formed by concatenating the 2-octet identifier
type code with variable-length data.
The RDATA for all type codes other than 0xffff, which is reserved for
future expansion, is formed by concatenating the 2-octet identifier
type code, the 1-octet digest type code, and the digest value (32
octets for SHA-256).
< identifier-type > < digest-type > < digest >
The input to the digest hash function is defined to be:
digest = SHA-256(< identifier > < FQDN >)
The FQDN is represented in the buffer in the canonical wire format as
described in [9], Section 6.2. The identifier type code and the
identifier are related as specified in Section 3.3: the identifier
type code describes the source of the identifier.
A DHCPv4 updater uses the 0x0002 type code if a Client Identifier
option is present in the DHCPv4 messages and it is encoded as
specified in [6]. Otherwise, the updater uses 0x0001 if a Client
Identifier option is present, and 0x0000 if not.
A DHCPv6 updater always uses the 0x0002 type code.
3.5.1. Using the Client's DUID
When the updater is using the Client's DUID (either from a DHCPv6
Client Identifier option or from a portion of the DHCPv4 Client
Identifier option encoded as specified in [6]), the first two octets
of the DHCID RR MUST be 0x0002, in network byte order. The third
octet is the digest type code (1 for SHA-256). The rest of the DHCID
RR MUST contain the results of computing the SHA-256 hash across the
octets of the DUID followed by the FQDN.
Stapp, et al. Standards Track [Page 5]
RFC 4701 The DHCID RR October 2006
3.5.2. Using the Client Identifier Option
When the updater is using the DHCPv4 Client Identifier option sent by
the client in its DHCPREQUEST message, the first two octets of the
DHCID RR MUST be 0x0001, in network byte order. The third octet is
the digest type code (1 for SHA-256). The rest of the DHCID RR MUST
contain the results of computing the SHA-256 hash across the data
octets (i.e., the Type and Client-Identifier fields) of the option,
followed by the FQDN.
3.5.3. Using the Client's htype and chaddr
When the updater is using the client's link-layer address as the
identifier, the first two octets of the DHCID RDATA MUST be zero.
The third octet is the digest type code (1 for SHA-256). To generate
the rest of the resource record, the updater computes a one-way hash
using the SHA-256 algorithm across a buffer containing the client's
network hardware type, link-layer address, and the FQDN data.
Specifically, the first octet of the buffer contains the network
hardware type as it appeared in the DHCP 'htype' field of the
client's DHCPREQUEST message. All of the significant octets of the
'chaddr' field in the client's DHCPREQUEST message follow, in the
same order in which the octets appear in the DHCPREQUEST message.
The number of significant octets in the 'chaddr' field is specified
in the 'hlen' field of the DHCPREQUEST message. The FQDN data, as
specified above, follows.
3.6. Examples
3.6.1. Example 1
A DHCP server allocates the IPv6 address 2001:DB8::1234:5678 to a
client that included the DHCPv6 client-identifier option data 00:01:
00:06:41:2d:f1:66:01:02:03:04:05:06 in its DHCPv6 request. The
server updates the name "chi6.example.com" on the client's behalf and
uses the DHCP client identifier option data as input in forming a
DHCID RR. The DHCID RDATA is formed by setting the two type octets
to the value 0x0002, the 1-octet digest type to 1 for SHA-256, and
performing a SHA-256 hash computation across a buffer containing the
14 octets from the client-id option and the FQDN (represented as
specified in Section 3.5).

If the DHCID RR type is not supported, the RDATA would be encoded
[13] as:

3.6.2. Example 2
A DHCP server allocates the IPv4 address 192.0.2.2 to a client that
included the DHCP client-identifier option data 01:07:08:09:0a:0b:0c
in its DHCP request. The server updates the name "chi.example.com"
on the client's behalf and uses the DHCP client identifier option
data as input in forming a DHCID RR. The DHCID RDATA is formed by
setting the two type octets to the value 0x0001, the 1-octet digest
type to 1 for SHA-256, and performing a SHA-256 hash computation
across a buffer containing the seven octets from the client-id option
and the FQDN (represented as specified in Section 3.5).

3.6.3. Example 3
A DHCP server allocating the IPv4 address 192.0.2.3 to a client with
the Ethernet MAC address 01:02:03:04:05:06 using domain name
"client.example.com" uses the client's link-layer address to identify
the client. The DHCID RDATA is composed by setting the two type
octets to zero, the 1-octet digest type to 1 for SHA-256, and
performing an SHA-256 hash computation across a buffer containing the
1-octet 'htype' value for Ethernet, 0x01, followed by the six octets
of the Ethernet MAC address, and the domain name (represented as
specified in Section 3.5).

If the DHCID RR type is not supported, the RDATA would be encoded
[13] as:
\# 35 ( 000001c4b9a5b249651343158dde7bcc77169841f7a4243a572b5c283
fffedeb3f75e6 )
Stapp, et al. Standards Track [Page 7]
RFC 4701 The DHCID RR October 2006
4. Use of the DHCID RR
This RR MUST NOT be used for any purpose other than that detailed in
[1]. Although this RR contains data that is opaque to DNS servers,
the data must be consistent across all entities that update and
interpret this record. Therefore, new data formats may only be
defined through actions of the DHC Working Group, as a result of
revising [1].
5. Updater Behavior
The data in the DHCID RR allows updaters to determine whether more
than one DHCP client desires to use a particular FQDN. This allows
site administrators to establish policy about DNS updates. The DHCID
RR does not establish any policy itself.
Updaters use data from a DHCP client's request and the domain name
that the client desires to use to compute a client identity hash, and
then compare that hash to the data in any DHCID RRs on the name that
they wish to associate with the client's IP address. If an updater
discovers DHCID RRs whose RDATA does not match the client identity
that they have computed, the updater SHOULD conclude that a different
client is currently associated with the name in question. The
updater SHOULD then proceed according to the site's administrative
policy. That policy might dictate that a different name be selected,
or it might permit the updater to continue.
6. Security Considerations
The DHCID record as such does not introduce any new security problems
into the DNS. In order to obscure the client's identity information,
a one-way hash is used. Further, in order to make it difficult to
'track' a client by examining the names associated with a particular
hash value, the FQDN is included in the hash computation. Thus, the
RDATA is dependent on both the DHCP client identification data and on
each FQDN associated with the client.
However, it should be noted that an attacker that has some knowledge,
such as of MAC addresses commonly used in DHCP client identification
data, may be able to discover the client's DHCP identify by using a
brute-force attack. Even without any additional knowledge, the
number of unknown bits used in computing the hash is typically only
48 to 80.
Administrators should be wary of permitting unsecured DNS updates to
zones, whether or not they are exposed to the global Internet. Both
DHCP clients and servers SHOULD use some form of update
authentication (e.g., [12]) when performing DNS updates.
Stapp, et al. Standards Track [Page 8]
RFC 4701 The DHCID RR October 2006
7. IANA Considerations
IANA has allocated a DNS RR type number for the DHCID record type.
This specification defines a new number-space for the 2-octet
identifier type codes associated with the DHCID RR. IANA has
established a registry of the values for this number-space. Three
initial values are assigned in Section 3.3, and the value 0xFFFF is
reserved for future use. New DHCID RR identifier type codes are
assigned through Standards Action, as defined in [5].
This specification defines a new number-space for the 1-octet digest
type codes associated with the DHCID RR. IANA has established a
registry of the values for this number-space. Two initial values are
assigned in Section 3.4. New DHCID RR digest type codes are assigned
through Standards Action, as defined in [5].
