LIRs have direct circuit-level (or equivalent) relationships with the 
address users. RIRs do not.

It would be very unusual for someone to have provider-assigned space and 
no ongoing contact or billing relationship with the provider, whereas 
legacy space in ARIN's database is exactly like that.

How can the prior registrant initiate a dispute in time if they weren't 
aware of a hijacking and subsequent immediate reclaimation?
