in reply to Reliable FQDN from IP
Net::Domain is core:
use strict; use warnings; use Net::Domain qw( hostfqdn ); my $host = hostfqdn(); print "$host\n";
Tested under Solaris, Perl 5.8.8
Update: Obviously this is for the current host, sorry if this doesn't actually answer the question. I'll never post another node while waiting for a hospital appointment to start.
