Obviously I didn't make it clear what is the problem in my previous post. So far I got the following 2 replies: "The NIC should allow for dummy [default] nameservers and allow the technical contact of a nameserver to remove his or her nameservers from a domain without requiring an administrative ack." Yes, but we are not the technical nor the admin contact for these domains; we just provide the IPs. What I propose is that the tech or admin contact of the NETBLOCK has authority to delete the host registration by virtue of the IP being his. "If the IP's are allocated to you, what's it matter where your old customer still points their NS? Just remove the old customer from all of your db's and reallocate your IP's elsewhere." We've been doing precisely that, and that's where the problem comes in. The new customer cannot register his nameservers because the IP is already registered as a nameserver. Then he complains, we look like idiots, and we have to give him other IPs to use. jcomeau@world.std.com aka John Otis Lene Comeau Home page: http://world.std.com/~jcomeau/ Disclaimer: Don't risk anything of value based on free advice.
