This code has only been tested on a Digital KZPCA adapter in an Alpha

the unwary if the code were called in slightly different ways.
1) In ufs_bmaparray() the code for calculating 'runb' will stop one block
short of the first entry in an indirect block. i.e. if an indirect block
contains N block numbers b[0]..b[N-1] then the code will never check if
b[0] and b[1] are sequential. For reference, compare with the equivalent
code that deals with direct blocks.
2) In ufs_lookup() there is an off-by-one error in the test that checks
if dp->i_diroff is outside the range of the the current directory size.
This is completely harmless, since the following while-loop condition
'dp->i_offset < endsearch' is never met, so the code immediately
does a second pass starting at dp->i_offset = 0.
3) Again in ufs_lookup(), the condition in a sanity check is wrong
for directories that are longer than one block. This bug means that
the sanity check is only effective for small directories.

we get the com address. If so, we go ahead and return. Bruce thinks
there's a bug in the pccard layer that it terminates devices with
extreme prejustice rather than letting them deside for themselves when
to terminate (and he's likely right). This fix doesn't change that,
but instead works around it by checking for NULL pointers at more
places than before.
The detach routine still calls functions at interrupt level that
aren't reentrant. In theory this could cause a problem, but none
showed up in practice. Future versions should correct this problem,
likely by making the detach process a thread/process at the pccard
level. NEWCARD will do this, and the current pccard layer should
likely be modified to that as well, should it live long enough.
A few style nits of the same form that were in my original patch sent
off to bde were also fixed as part of this process. Mostly use of

Now most big problem of IPv6 is getting IPv6 address

6to4 solve the problem. 6to4 addr is defined like below,
2002: 4byte v4 addr : 2byte SLA ID : 8byte interface ID
The most important point of the address format is that an IPv4 addr
is embeded in it. So any user who has IPv4 addr can get IPv6 address
block with 2byte subnet space. Also, the IPv4 addr is used for
semi-automatic IPv6 over IPv4 tunneling.
With 6to4, getting IPv6 addr become dramatically easy.
