my $res = Net::DNS::Resolver->new(nameservers => [$ns], recurse => 0); fails to properly set the nameserver when an IPv6 address is given: <dns1.peak.org> [108] # ndnsrrv6 Net::DNS version 0.74 check peak.org on 2607:f678::56 no nameservers check peak.org on 2001:4801:7817:72:7338:e87f:ff10:ba4c no nameservers check peak.org on 207.55.16.56 peak.org serial 2014031101 <dns1.peak.org> [109] # host -t soa peak.org 2001:4801:7817:72:7338:e87f:ff10:ba4c Using domain server: Name: 2001:4801:7817:72:7338:e87f:ff10:ba4c Address: 2001:4801:7817:72:7338:e87f:ff10:ba4c#53 Aliases: peak.org has SOA record ns1.peak.org. hostmaster.peak.org. 2014031101 300 900 604800 300 <dns1.peak.org> [110] # host -t soa peak.org 2607:f678::56 Using domain server: Name: 2607:f678::56 Address: 2607:f678::56#53 Aliases: peak.org has SOA record ns1.peak.org. hostmaster.peak.org. 2014031101 300 900 604800 300

Suggest you try this. If you get different result, the problem lies in your IPv6 setup, not Net::DNS. #!/usr/bin/perl use Net::DNS; my $ns = '2607:f678::56'; my $res = Net::DNS::Resolver->new( nameservers => [$ns], recurse => 0 ); $res->debug(1); $res->print; ;; RESOLVER state: ;; domain = ;; searchlist = ;; nameservers = 2607:f678::56 ;; port = 53 ;; srcport = 0 ;; srcaddr = 0.0.0.0 ;; tcp_timeout = 120 ;; retrans = 5 retry = 4 ;; usevc = 0 stayopen = 0 igntc = 0 ;; defnames = 1 dnsrch = 1 ;; recurse = 0 debug = 1 ;; force_v4 = 0 (IPv6 Transport is available) ============================= ;; Trying to set up a AF_INET6() family type UDP socket with srcaddr: :: ... done ;; setting up an AF_INET() family type UDP socket ;; send_udp(2607:f678::56#53) Show quoted text

OK, IO::Socket::INET6 wasn't installed, so please change this ticket to request a more helpful error message. Thanks!
