Andy, The existence of 8.f.0.f.1.f.1.0.8.a.b.0.1.0.0.2.ip6.arpa as an authoritative zone on the server has higher relevance than the delegation inside another zone. The answer comes from the authoritative zone, no need to follow the delegation.

Only open attachments or links that you are expecting from a known sender. Hi Don, Yes. If you want actual names to look at, these zones are both present on the same servers: 1.f.1.0.8.a.b.0.1.0.0.2.ip6.arpa 8.f.0.f.1.f.1.0.8.a.b.0.1.0.0.2.ip6.arpa However, the presence of 8.f.0.f.1.f.1.0.8.a.b.0.1.0.0.2.ip6.arpa is a mistake and in the mean time someone has changed the delegation inside 1.f.1.0.8.a.b.0.1.0.0.2.ip6.arpa to be: 8.f.0.f NS ns-auto.bitfolk.com. A query for, say: 2.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.8.f.0.f.1.f.1.0.8.a.b.0.1.0.0.2.ip6.arpa. IN PTR is answered NXDOMAIN because it does not exist inside the 8.f.0.f.1.f.1.0.8.a.b.0.1.0.0.2.ip6.arpa zone file, instead of following that delegation to ns-auto.bitfolk.com.
