RPKI · ASPA

Declared transit providers

3 declared

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

ASNetworkASPARouting paths
AS3356Level 3 Parent, LLCDeclaredObserved
AS7018AT&T Enterprises, LLCDeclarednot observed
AS32505ConterraDeclaredObserved

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

20 objects · 11 not announced

Route objects naming AS23228 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.
