Reverse DNS Resolving Tool (historic now, see ipv6calc for more)

IPv6 addresses for DNS reverse lookup with nslookup are long and can be full of mistakes.
Here is a small Perl program, called ip6_int, written by Keith Owens <kaos@ocs.com.au>

Information:

nslookup treats IPv4 addresses (a.b.c.d) as a special case and

internally converts them to d.c.b.a.in-addr.arpa. Alas it does not do

the same thing for IPv6 addresses. Try the perl script below, released

under GPL. nslookup -type=any `ip6_int 3ffe:400::/24` yields

This Perl program is now historic, see ipv6calc for more and use it like shown:

# nslookup -q=ANY `ipv6calc -r 3ffe:400:100:f101::1/48`

Your connection is via: IPv4
Your address: 216.73.216.55
