No need to be sorry, this is what comment periods are for ;-) I will only put in that this document deals with the 256 class C delegation. As you can make up from the title, this only deals with blocks delegations, not with single C delegations. We have to write a short document how we handle single class C delegations (probably just a description that we will use the rev-srv fields. * > 8.

My gut feeling would be we add them anyway. If the nets are not yet active, there is probably no need to do reverse lookups anyway, so noone would notice. On the other hand this would clash with the constraint that we would like to see all servers working before we add them ... I think we can put some intelligence in the rev-srv field to DNS record generator to get around these things.

OK, has been changed to: The NCC also suggests that similar procedures are set up for the delegation of reverse zones for individual class C networks from the registries to individual organisations.
