I see. So if you tell the customer that they need to renumber, then they tell you to stuff it and switch to a new provider who... tells them that they must renumber out of your soon-to-be-reassigned address space.
I just don't see this as a realistic example of a situation in which a renumbering ISP is at a severe business disadvantage. In fact I can't remember ever seeing any such realistic example nor do I ever remember hearing of a case in which an ISP lost a significant amount of business because of renumbering.
We have renumbered out of two /20's and 2 /19's and, although we haven't lost any dedicated customers, our time investment in the process has been unreal. In several instances we had to go onsite and do the renumbering for them. Of course, the first time you go onsite, the tech guy isn't there, so that's half a day for two people lost. Then, the next time you go, he doesn't have the passwords to the server, so you have to come back again... And, because this is something we are requiring them to do, we can't charge them for it. Let's not forget to mention the 10,000 dialup customers who have to change their DNS numbers. We have sent snail-mail and e-mail over and over again, yet only about 1/3 of that 10k have actually made the change away from the old numbers. How many of those customers do you think we'll lose when we officially turn off the old ip's? Mike Michael K.
