(usagi-users 03518) dns reverse lookup issues

[Sanjib Das <Sanjib.Das@xxxxxxxxxxxxxxx>]

Hi

As per RFC 3364 :    Any name
server which does not support bit label will return error

As per RFC 3363:    This document
moves the A6 and Bit label specifications to experimental status.

In few docs (http://ftp.teledanmark.no/pub/networking/dns/Bv9ARM.pdf)
(section 4.8.3) i got 
"nibble format to look up names is deprecated,
it is supported for backwards
compatiblity with existing IPv6 applications."

Now as per the current bind release (9.3.1),
in dig.c  
the -n option is deprecated. It is same with
bind (9.2.4) also which i'm running.

Now if it is deprecated (as per bind), then
all the servers should be aware
of bit label reverse lookup. then its bit
contradictory with RFC 3364 statement.

the problem with me is like i cannot send
reverse queries (qtype = PTR) with -n option,
even if i want i may have to install lower
version of dig or else i will have to implement the same.
I dont know exactly which version of bind
supports the nibble label facility...
plz comment....

thanks & regards

Sanjib
