[AusNOG] IPv6 rDNS ReDelegation

[Beeson, Ayden]

Just having a look at APNIC's portal, their IPv6 reverse DNS delegation form even has this:
Example:
2001:dc0:2001::/48
2001:a130::/31

So unless their examples are completely false, you CAN do a smaller range.

We have a /32, however my attempts to create something smaller are just being given an error saying it must match our range to the nearest nibble boundary....

Thanks,
Ayden Beeson

I agree that this is poor.

Given we have a /22 IPv4 from APNIC, and we can delegate each individual /24 to different rDNS servers  So one thinks to himself, why can we not delegate a smaller /40 or /48 from that /32 in the same concept :D

I'm surprised that they can't delegate lower than a /32, they give the /32's out to ISP's but give smaller chunks to other applicants (/40 or /48 from memory) so I'd assume they can handle that for them, why not you?

Either way, the lazy way would be to set up the customer as the master and your DNS server as the slave, then keep the APNIC lookups coming to you, but it's a pretty slack workaround and will require you to set things up every time they change something....

Somebody else might have a better idea than that; off the top of my head I don't have one yet.

Thanks,

As you are most likely aware, a provider like yourself is issued with a /32 IPv6 from APNIC,

We are able to set the rDNS servers for this entire /32 to our windows 2008 DNS server for PTR records,

However I have issued one of our customers with a /40 and wish to send this /40 to their rDNS server.

I've been told by APNIC that its not possible to delegate any lower then a /32 from their end, but it is possible from the DNS server to push the zone further down to other sets of name servers.

I was wondering if anybody on list has ever done this in the past, and how they managed to achieve it?

We have setup our /32 in our DNS server but now wish to send a /40 of the /32 to a different rDNS server

I hope you get what i mean, and hope somebody on/off list can assist.

TIA
