RPKI · ROAs
Route origin authorisations
Signed statements by address holders that AS37154 may originate these prefixes, up to the maximum length shown.
ROA-based and RPKI-valid-only prefix lists for routers are on asn.ipinfo.app.
RPKI · ASPA
Declared transit providers
No ASPA record This network has not published an ASPA object. ASPA lets a network sign the list of its transit providers, so routers can reject paths that route through anyone else (route leaks). Only a few thousand networks publish one so far, so its absence is normal.
IRR
Registered route objects
Route objects naming AS37154 as origin, across RADb, the RIR registries, ALTDB and NTTCOM. Objects that are registered but not announced come first: a stale object lets anyone who can spoof this origin through an IRR-built filter.
