Sorry, I was in a rush when I typed the above (we're in the middle of an
imminent ice storm, and I've been trying to get systems up for realtime
radar analysis). You are partially correct - while you do have to change
your name (so to speak) when you change your IP address, and it may be
inefficient, it's all we've got. I'm open to suggestions (as is the rest
of the net) to change, although I don't think this is the proper forum for
mud-slinging.
While it is technically correct that if your IP address changes, your name
changes, companies will often get a block or two of class C addresses but
not assign names to them. NIC says that those addresses "belong" to
organization X, but you may not necessarily be able to get there by name.
If the organization will assign your name to one of their IP addresses,
then you don't have to change your name. Does that make more sense?
