RPKI hygiene: D how networks compare →

20.3% of checked blocks have valid RPKI ROA coverage (13 of 64)

Possible discrepancies (1)

These blocks are registered to Washington State University 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.
