IPv6 rDNS (PTR) for entire /64 range

[Mattie]

Hi,

I have an IPv6 /64 block, and the rDNS is delegated to my own nameservers. I'd like to default ALL ip addresses to "unused.xxx.xxx" and just for the ones I use I'll create a separate entry.

But:
How can I do that using bind?
I already tried:

*.123.123.123.ip6.arpa
123.123.123.ip6.arpa

But it does not seem to be working, simply adding 1 single address works fine. I've also found the "generate" option but that seems to be more for IPv4 as it only supports numbers.

Anyone a clue?

Not sure honestly, but maybe you may need to create a script and use APIs to do so.

Best regards

Yes that is possible, however that would result in a very very very large file. I might switch to powerdns, as far as I can tell they do support "*"

You may ask a FR to DA staff (or support via their ticketing system) to add the functionality, maybe there is already and we simply don't know

Best regards

Tried doing it manually according to: https://www.sixxs.net/faq/dns/?faq=reverse but it does not seem to work.
(well that guide does not talk about wildcards but hey, it should work right?)

Sorry for the late reply, but thanks using this method seems to work Will test a few cases over the weekend but so far so good!
