Its obviously not a technical, but an attitude problem. People have the mindset that they "fought" for getting a net number, and they take pride in ownership. A good part of the problem is that those people got the address in the mindset of "my address lasts forever," rather than being a convenience measure. There is no guarantee you keep your phone number either, if the phone company beliieves they have a good reason to change it. Look at the area code splits in, e.g., CA. Or is you move to "another area." Postal address the same. If you move to another location, you mail your business partners and customers a new name-to-address mapping. The other issue is an overblown horror about renumbering (even if the same names are kept). In reality it is really not THAT much of a big deal (yes, I have done it several times before), if planned for right, and if at most one has to do it only every few years. Sure it can be quite a bit of work, BUT SO WHAT? Networking does not come for free, it is a high maintenance item, just like trees in the back yard. There sure is a solution to not having to worry about the work with the trees any more. People just have to learn that in an environment as fastly moving as The Network, things cannot be static, and they have to expect some maintenance work, and some of it may be a pain in the butt. Cost of doing business. Just include the budget for "1 renumbering every 3 years" as a line item. I cannot understand the pride people take in exponential grows, and a belief in things being static and maintenance free at the same time. Guess the *real* problem is that nobody has the guts in this anarchic Internet environment to put his butt on the line and force the issue.
