Ah. Yes, do tell 500000 customer and 4 diferent billing/provisioning system type ISPs to renumber if they change upstream provider. That will make you popular :)
If you have 500000 customers, there's no discussion that you can get your own address block (and keep it).
Granted, that example was a bit extreme :) However, most ISPs/networks tend to fiercely opose renumbering.
The interesting problem is how to make end user (!) multihoming work without putting the burden on everybody *else*. I am NOT interested in seeing 20.000 small multihomed end customers in my routing tables, because in the end everything goes over one of two possible links anyway.
That's cause you only have 2 links. Some people have 20. With 3 diferent routing policies. And that's not even counting costumer links. Geting the Americas, Africa, Europe and Asia routes blows dead bears in that situation.
Now really, I rather have IPv6 now, evaluate the real practical problems and fix them than spending years not having IPv6 cause the fix to a would-be problem introduces unworkable problems itself.
So go and get an allocation :-)
Aparently I'm not big enough. My costumers are though. I'm supposed to get a /48 from one my 5 or 6 upstream providers and then announce it to a number of IXs. It's got to be a brave new Internet when in the name of aggregation upstream providers can't get address space.
