RPKI hygiene: B how networks compare →
81.8% of checked blocks have valid RPKI ROA coverage (9 of 11)
Possible discrepancies (1)

These blocks are registered to Technische Universitaet Dresden 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.
