for PTR records, are the 1234 chunks used, or is everything split
out so it would be 4.3.2.1?

It depends.  "Production" addresses (e.g. 2001::) uses "ip6.arpa"
appended to the reverse nibbles:

2001:1234:5678:9abc::1  -->
1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.c.b.a.9.8.7.6.5.4.3.2.1.1.0.0.2.ip6.arpa.

whereas testing addresses (6BONE, e.g. 3ffe::) uses "ip6.int"
appended to the reverse nibbles:

3ffe:1234:5678:9abc::1  -->
1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.c.b.a.9.8.7.6.5.4.3.2.1.e.f.f.3.ip6.int.
