Network trust

what's this?
RPKI hygiene: C how networks compare →
78.5% of checked blocks have valid RPKI ROA coverage (51 of 65)
Possible discrepancies (1)

These blocks are registered to AARNet 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.

195.48.144.0/24 /24 authorized for AS1836 — green.ch AG
Routed via provider/NREN (3)

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.
