So it includes the glue >record X. OK, so I ask for foo.example and I get ; answer foo.example NS ns.bar.example ; additional ns.bar.example AAAA 2001:0DB8:0000:000b::2 Does it check that's the right value for ns.bar.example? How about with DNSSEC? I suppose I still don't see the benefit of trying to make some loops work when we know that we can't make cross-zone loops work. R's, John
