Can a PI assignment be converted into a PA allocation?
Yes. PI assignments can be converted on request to PA allocations. LIRs can email lir-help _at_ ripe _dot_ net to make the request.
In order to be converted, the assignment must be correctly registered with the RIPE NCC to the same legal entity that is registered as an LIR.
IPv4 PI assignments consisting of multiple prefixes can be split on request and then converted into allocations.
