what's this?
RPKI hygiene: B how networks compare →
94.4% of checked blocks have valid RPKI ROA coverage (67 of 71)
Possible discrepancies (1)

These blocks are registered to Internet2 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.
