[dns-wg] Secondary service on ns.ripe.net for reverse delegations.

As mentioned in my presentation at RIPE 54 last week we have become  
aware that there is an inconsistency between ipv4 and ipv6 with  
regard to obtaining reverse delegation.

The reverse delegation procedure listed at http://www.ripe.net/rs/ 
reverse/reverse_howto.html has the following listed:

Secondary Service by the RIPE NCC

         For IPv4: If your zone is a /16 reverse zone, you will need  
to set up ns.ripe.net as a secondary server
         For IPv6: If your zone is a /32 reverse zone, you may use  
ns.ripe.net as a secondary

-----snip

We think it would be a good idea to address this inconsistency, this  
could be done in several ways including but not limted to:

Make ns.ripe.net mandatory on ipv4 and ipv6 delegations
Make ns.ripe.net optional on ipv4 and ipv6 delegations
Discontinue the secondary service on ns.ripe.net for new delegations.

Our suggestion and preference would be to make ns.ripe.net optional  
on both ipv4 and ipv6 delegations.

We would welcome and encourage input from the dns community on this  
subject.

Regards

Brett
