it seems better to transfer the block. Although ISPs are under no obligation
to do so, the upstream provider will most likely not be willing either. Of
course, the answer is to have a portable IP Class, which is almost impossible to
acquire now. If there is a large network involved (enterprise) it locks them
in to a service provider they may wish to leave. There should be a cleaner
method to accomplish it. Perhaps the gaining ISP should take on the challenge
of renumbering the network.
In any case, it should not be that painful for a network
to change providers. In my limited experience, IP blocks have been transferred
fairly easily with a little coordination on both sides. Of course, it depends
largely on the expertise of the network administrators of all three entities - losing
ISP, gaining ISP, client network. Then there is also the competence of the
upstream techs - abysmal many times.
