I disagree. I have personally renumbered two relatively small ISPs
(including customers!) a total of three times. That would be 5 - 20
routers and 10 - 40 servers.

When compared to a lazy afternoon of doing nothing, renumbering is a lot
of work. When compared to the routine maintanance that happens anyway over
a period of several months, the added trouble of renumbering is fairly
negligible.

BTW: changing domains isn't much of a problem: just register a new address
for your name server.
