RPKI hygiene: A how networks compare →

97.3% of checked blocks have valid RPKI ROA coverage (1,946 of 2,000, sampled from 4,449)

Wholesale/transit re-announcements (42)

These blocks are registered to Comcast Cable Communications, LLC but cryptographically authorized across 6 different networks — typical for a large wholesale or transit carrier whose address space is substantially re-announced by downstream customers under their own ASNs, not individually noteworthy.
