RPKI · ASPA

Declared transit providers

1 declared

This network has signed an ASPA record naming its transit providers. Each is compared against the upstreams observed in routing paths.

ASNetworkASPARouting paths
AS17660DrukNet ISPDeclaredObserved

An observed upstream that is not declared is not necessarily a leak: our upstream inference cannot tell a transit provider from a peer seen in the same position. A declared provider that is never observed is usually a backup path.

IRR

Registered route objects

33 objects · 25 not announced

Route objects naming AS18024 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.
