[AusNOG] IPv6 rDNS ReDelegation

[Damien Gardner Jnr]

Should be the same as delegating a sub-domain, or a /24 out of a /16 - 
put the NS records into your zone for the sub-zone(s) ?

aka say you have 2400:1234/32, and you have punted 2400:1234:56/40 to 
your customer

You have a DNS zone for 4.3.2.1.0.0.4.2.ip6.arpa.

In there' you'll have the following entries:

6.5     IN NS ns0.customer.com.
6.5     IN NS ns1.customer.com.

And your customer will then configure a zone for 
6.5.4.3.2.1.0.0.4.2.ip6.arpa on their DNS servers.

Well, pretty sure that's it..  Someone who's done more IPv6 will surely 
pipe up if I'm wrong :)

Cheers,

Damien
