We developed a web/mysql-based front-end that our noc uses for all DNS
ops, so the NOC never touches zone files directly. So it was easy to
just add a feature that provides additional syntax for ipv6 PTRs...
So for example in zone
0.0.0.0.d.c.b.a.8.B.D.0.1.0.0.2.ip6.arpa
we can enter
0000:0000:0000:0003 PTR foo.com.
and it will reverse the nibbles/remove the ":"s and put in the "."s
and get generated into a zone file as needed:
3.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.d.c.b.a.8.B.D.0.1.0.0.2.ip6.arpa PTR foo.com.
(of course you can enter x.x.x.x... syntax too)
Having a front-end also lets you do all sorts of other sanity-checking
with instant feedback to avoid choking up BIND, depending on the skill
level of your target "DNS admin".
