RPKI hygiene: B how networks compare →
85.2% of checked blocks have valid RPKI ROA coverage (1,703 of 2,000, sampled from 2,843)
Wholesale/transit re-announcements (548)

These blocks are registered to RCN Corporation but cryptographically authorized across 23 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.
