(usagi-users 03518) dns reverse lookup issues

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
