Network trust

what's this?
RPKI hygiene: A how networks compare →
100.0% of checked blocks have valid RPKI ROA coverage (5 of 5)
Possible discrepancies (2)

These blocks are registered to GRS 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.

185.177.156.0/23 /23 authorized for AS200645 — Fara Ertebat Mabna PJS
185.177.158.0/23 /23 authorized for AS200645 — Fara Ertebat Mabna PJS
Routed via provider/NREN (1)

These blocks are cryptographically authorized for this organisation's national research & education network or transit provider — expected topology for an institution that routes through it, not a discrepancy.
