I second the use of DNS instead of whois.

but himanh said...

Basically checking if any of my domains are transferred or still with me.

So, if himanh asks his DNS server, he will always believe the domain is with him. Just wanted to throw in this advice.

If you want to make it work, you need to ask a root name server for the delegation information to reach to the name servers. For instance...

#!/usr/bin/perl -w use strict; use NetAddr::IP; use Net::DNS::Resolver; my $res = new Net::DNS::Resolver; # For domains in CCTLDs, you need to ask root-servers.net instead # and follow the delegation chain. $res->nameservers(NetAddr::IP->new("g.gtld-servers.net")->addr); for my $dom (map { chomp; $_ } <DATA>) { my $packet = $res->query($dom, 'NS'); # No answer received... unless ($packet) { warn "No response for $dom\n"; next; } # A DNS answer (response) was received but ... my @answer = $packet->answer; # ... it might not contain real answers ... unless (@answer) { warn "Response packet contains no answer section for $dom\n"; next; } # ... or it might be what I am looking for. for my $s (@answer) { next unless $s->type eq 'NS'; print "$dom: ", $s->nsdname, "\n"; } } __END__ google.com yahoo.com aol.com

will answer the right people for the 7 gTLDs. This is only slightly tested and you might need to change the gtld server to use.

This code should give you something to start playing with...
