RPKI · ROAs

Route origin authorisations

0 ROAs

Signed statements by address holders that AS21302 may originate these prefixes, up to the maximum length shown.

No ROA names this AS as an authorised origin.

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

17 objects · 8 not announced

Route objects naming AS21302 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.
