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
AS22381SAMM TECNOLOGIA E TELECOMUNICACOES S.ADeclaredObserved
AS28260ALTA REDE CORPORATE NETWORK TELECOM LTDA - EPPDeclaredObserved
AS53181Avanca Telecom e Servicos LTDADeclaredObserved

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

18 objects · 0 not announced

Route objects naming AS273709 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.
