[arin-ppml] Unallocated IPs

[David Huberman]

They're probably either:

In the returned, revoked, or held buckets (scheduled for reissue per arin's processes); or

They don't belong to ARIN and are bits and pieces that belong to a different RIR

Hey,

I was doing some scanning of IP ranges and it appears that there are hundreds, if not thousands, of /21s and equivalents that are not assigned to anyone, yet do not appear on any ARIN inventory counters. Is this an oversight in the WHOIS or has ARIN 'forgotten' about these ranges?

For reference, here are some of the blocks:
