I don't mean to keep beating this to death but I am curious to get to the bottom
line of what you are trying to accomplish overall.
Now you are saying you want reserved IP's implemented automatically
when someone is issued IP's for name servers.
So If I may ask, Do you plan on offering dedicated IP's for everyone that wants
to run their own private name server?
I am just very perplexed as to your goal in doing this. Reserving IP's and using them
only for name servers is not a good use of resources and I find it highly unusual.
Perhaps if you explained why you are wanting such a thing and maybe your intentions,
maybe we offer better suggestions.
So to keep it simple, I think we know what you are wanting to do, but the need to
do this so often as to automate this?
