[AusNOG] IPv6 rDNS ReDelegation

[Thomas Jackson]

You'll need to set up an NS record on your DNS server delegating the /40 to
their DNS server(s). In short, queries for "their" /40 will first come to
your DNS server, at which point it will tell them to go off and find the
customer's DNS servers for the information.

I believe the way to do it in Windows DNS is to create a "New Delegation"
from the DNS manager.

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
