questions about ARIN ipv6 allocation

[Edvinas Kairys <edvinas.email () gmail com>]

Hello,

We're setting up IPv6 network is USA. Our company has branches and
different legal entities in EU and US. We've some ipv6 PI subnets already
allocated by RIPE for EU datacenters. I have few questions:

1) Is it possible to reuse some portion of RIPE allocated ipv6 addresses in
USA ? Or we need to ask for the new ones by requesting in ARIN ?
2) Can i request in ARIN just ipv6 subnets for USA DCs, but to use the same
AS number which was allocated by RIPE in EU ?

Thanks
