Use a computational dns server. One that uses a pattern for forward and reverse, then just have exemptions.

http://member.wide.ad.jp/~fujiwara/v6rev.html is anexample that seems to work quite well.

Having two SQL records (AAAA & PTR) for every IPv6 address is not going to scale very well.
That's a lot of rows if you have /32

I'm sure there is a much better way of doing this.

	Yep. Admittedly not a lot of records, but there is no practical limit with that kind of set up.

		Do you have a reverse entry and matching AAAA record for every IPv6 Address in your network?  or at least the ones in use?

			I don't allow customers to manage their own records but that is due to no one wanting to do it, not because I can't.

				I'd be more interested to know how people are solving the reverse DNS problem in IPv6. 

				Ideally customers should be able to self manage any static entries they have and have a fall back for everything else, with matching AAAA of course.

				I just got an IPv6 PTR record done by Telstra and it took several weeks to provision.

				I'm thinking of have a SQL database with PowerDNS (or ProBind) for the statics and LUA or Perl plugin for the dynamics.

					Hi All, we are looking at DNS Server options for an ISP business of around 10,000 customers using ADSL, NBN, Ethernet, and Wireless services.

					 

					Currently the BIND solution which is in place is working but we are wondering what people would suggest as a next step that is easy to manage and cost effective to implement and that can grow with the business to handle 20-50,000 services eventually.

					 

					Any advice would be appreciated.

					 

					Thanks
