what's this?
RPKI hygiene: B how networks compare →
84.2% of checked blocks have valid RPKI ROA coverage (64 of 76)
Possible discrepancies (14)

These blocks are registered to COLNET but cryptographically authorized for a different, unrelated network (1 distinct holder) — often M&A history, multi-homing, or outsourced/managed hosting, occasionally worth a closer look.
