OTOH, if the requirement is "must have PTR" and/or "organisation fwd
domain name should show up in PTR RDATA" then wildcards have a place. And
yes, BIND loads and answers, as expected.
*.4.4.3.0.5.a.0.0.8.b.d.0.1.0.0.2.ip6.arpa. PTR a.node.on.vlan344.namn.se.
=2E..will work just fine, for instance. I did it for a 200+ segment LAN
party, couple years ago. And as is usual with wildcards, if you do need
to insert a real record, it will take over just as expected.
