Do I have to seek approval from the RIPE NCC before entering a SUB-ALLOCATED PA object into the RIPE Database?
No, it is your space to sub-allocate as you see fit. Responsibility for errors and problems arising from the use of SUB-ALLOCATED PA remains entirely with the LIR concerned. SUB-ALLOCATED PA "status:" objects are counted towards the 80% usage requirement when evaluating requests for an additional allocation.
