what's this?
RPKI hygiene: A how networks compare →
95.6% of checked blocks have valid RPKI ROA coverage (173 of 181)
Possible discrepancies (1)

These blocks are registered to Extreme Broadband 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.
