This article explains what Verisign has done for lookups of non-existing host names. http://www.theregister.co.uk/content/6/32852.html If you are using the: require_resolvable_fromhost plugin, it just stopped working because all host names resolve to an IP whether the exist or not.
I made a quick patch so the loop in the plugin now reads: if ($query) { foreach my $rr ($query->answer) { # if this host, its the verisign catch all domain address # for non-existing domains # see: http://www.theregister.co.uk/content/6/32852.html if ($rr->type eq "A" && $rr->address eq "64.94.110.11") { print STDERR "Verisign catchall IP for: $host\n"; return 0; } return 1 if $rr->type eq "A" or $rr->type eq "MX"; } } Jim James H.
