Network trust

what's this?
RPKI hygiene: A how networks compare →
100.0% of checked blocks have valid RPKI ROA coverage (69 of 69)
Possible discrepancies (35)

These blocks are registered to Universiteit Maastricht but cryptographically authorized for a different, unrelated network (2 distinct holders) — often M&A history, multi-homing, or outsourced/managed hosting, occasionally worth a closer look.
