If you have PI you should have agreement with your sponsoring LIR (or RIPE NCC) and with several providers (taking into consideration multihoming). If all of them (wrongly assumed as "either" by you) choose not to play agree, then your multihoming plans won't work. What's the difference then with assigned PA block? Alexey Ivanov tried to say that there are several LIRs that are not providers and their MAIN business is provide numbers (IPs, ASns...). They are of the same reliability as sponsoring LIRs and won't leave you without their service, because they want your money. More than that - there MANY providers, LIRs, carriers... which gives you enormous possibilities to change any of the party without any problem. No business harm at all.

But your original point was: "Because you can't multihome PA addresses." Yes, you can. ;-)

Please make your mind about your arguments.

You can, with the implicit agreement of the LIR who holds the allocation and the explicit agreement of a third party provider. If either choose not to play agree, then your multihoming plans either won't work (third party disagrees) or can be screwed up (LIR disagrees). Either way, it's not provider independent in any meaningful way and can lead to serious business harm if there is a breakdown in any of the arrangements. Nick
