	At interop, I picked up a mag where it was listed, now I got to 
go find it again.

	Yes, you are correct. I agree with you on this one.

	I see ISPs going down all the time. Plus, with all the new ones 
coming on line, they will not make it like the older times. Unless they 
can compete on service. Even though we are $8.50 more in one city, we get 
the customers from the other ISP everytime.

	Well, I guess it could be in a RFC
	Also, if you are able to get more IPs from the nic, you are in 
less of a chance to be a non routable route. Plus, there needs to be a 
way to get the ips cleaned up on the net.
