Tom Jones deb2aead4a Rename IPPROTO 33 from SEP to DCCP 
IPPROTO 33 is DCCP in the IANA Registry:
https://www.iana.org/assignments/protocol-numbers/protocol-numbers.xhtml

IPPROTO_SEP was added about 20 years ago in r33804. The entries were added
straight from RFC1700, without regard to whether they were used.

The reference in RFC1700 for SEP is '[JC120] <mystery contact>', this is an
indication that the protocol number was probably in use in a private network.

As RFC1700 is no longer the authoritative list of internet numbers and that
IANA assinged 33 to DCCP in RFC4340, change the header to the actual
authoritative source.

* Local port number conventions:
*
* When a user does a bind(2) or connect(2) with a port number of zero,
* a non-conflicting local port address is chosen.
* The default range is IPPORT_HIFIRSTAUTO through
* IPPORT_HILASTAUTO, although that is settable by sysctl.
*
* A user may set the IPPROTO_IP option IP_PORTRANGE to change this
* default assignment range.
*
* The value IP_PORTRANGE_DEFAULT causes the default behavior.
*
* The value IP_PORTRANGE_HIGH changes the range of candidate port numbers
* into the "high" range. These are reserved for client outbound connections
* which do not want to be filtered by any firewalls.
*
* The value IP_PORTRANGE_LOW changes the range to the "low" are
* that is (by convention) restricted to privileged processes. This
* convention is based on "vouchsafe" principles only. It is only secure
* if you trust the remote host to restrict these ports.
*
* The default range of ports and the high range can be changed by
* sysctl(3). (net.inet.ip.portrange.{hi,low,}{first,last})
*
* Changing those values has bad security implications if you are
* using a stateless firewall that is allowing packets outside of that
* range in order to allow transparent outgoing connections.
*
* Such a firewall configuration will generally depend on the use of these
* default values. If you change them, you may find your Security
* Administrator looking for you with a heavy object.
*
* For a slightly more orthodox text view on this:
*
* ftp://ftp.isi.edu/in-notes/iana/assignments/port-numbers
*
* port numbers are divided into three ranges:
*
* 0 - 1023 Well Known Ports
* 1024 - 49151 Registered Ports
* 49152 - 65535 Dynamic and/or Private Ports
