We appear to have a problem establishing simple matters of fact.

Slightly modifying my previous snippet:

        print 'Net::DNS ', Net::DNS->version, "\n";
        my $resolver = Net::DNS::Resolver->new();

        my @zone = eval { $resolver->axfr('net-dns.org') };
        print scalar(@zone), "\n";
        my $errorstring = $resolver->errorstring;
        print "errorstring is ", defined($errorstring) ? "defined\n" :


        Net::DNS 1.05
        errorstring is defined
