Can I determine if a given "hostname" is a CNAME via Perl
At work I have something like this..开发者_JS百科.
$ host www.something.com
www.something.com is an alias for some.other.address
some.other.address is an alias for one.more.address
one.more.address has address xxx.xxx.xxx.xxx
I would like a way, in Perl to put in www.something.com
and determine if it's a CNAME, A record, etc.
use Net::DNS qw();
my $query = Net::DNS::Resolver->new->search('conferences.yapceurope.org');
if ($query) {
foreach my $rr ($query->answer) {
next unless 'CNAME' eq $rr->type;
print $rr->cname;
}
} else {
warn sprintf "query failed: %s\n", $res->errorstring;
}
