Once you've been allocated your ASN and /32 subnet, is there any requirement that they continue to be used, or is it ok to sit on it for later use too?

My IP space is PA, it’s allocated by a LIR.

RIPE does have a requirement that you use your ASN, and that it’s multihomed.

Multihoming rule isn’t enforced (meaning a single upstream is fine), but they do require you to actually use it.
