I’m not sure I understand your point.  DNS is DNS.  It’s not the 1990s anymore and people should not be doing this 
without automation.

This should be done at the same time.  There’s plenty of people who have done this, so you shouldn’t have to build it 
yourself either, but you may want to.

Your central unit should be the subscriber and they should have the relevant attributes associated with them, be it IP 
history as well as account history.  You can have the DNS system sign on the fly if you have DNSSEC and that’s your 
concern.  IPv6 hosts still leave something to be desired for dynamic DNS entries, but looking at what happens behind 
Comcast as an example, there are no PTR records, eg:

2601:401:4:3000:71d1:cf8e:a951:xxxx -> x.x.x.x.1.5.9.a.e.8.f.c.1.d.1.7.0.0.0.3.4.0.0.0.1.0.4.0.1.0.6.2.ip6.arpa not 
found: 3(NXDOMAIN)

If you want to make it more user friendly, you can overload it like this:

openresolverproject.org has address 204.42.254.206
openresolverproject.org has IPv6 address 2001:418::7011:204:42:254:206
