This is from the examples section of Net::DNS :

use Net::DNS;
my $res   = Net::DNS::Resolver->new;
my $reply = $res->search("www.example.com", "A");
 
if ($reply) {
    foreach my $rr ($reply->answer) {
        print $rr->address, "\n" if $rr->can("address");
    }
} else {
    warn "query failed: ", $res->errorstring, "\n";
}

The search method in the resolver returns a packet object. Then the 'answer' method of that (from Net::DNS::Packet) "Returns a list of Net::DNS::RR objects representing the answer section of the packet." I've looked through the documentation for Net::DNS::RR and the module sourch but can't find the description of what the 'can' method is. The example runs without errors while using strict and warnings. Any suggestions?
