Declared transit providers

4 declared

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

AS	Network	ASPA	Routing paths
AS1299	Arelion Sweden AB	Declared	not observed
AS3257	GTT Communications Inc.	Declared	not observed
AS3320	Deutsche Telekom AG	Declared	not observed
AS3356	Level 3 Parent, LLC	Declared	not observed
AS56655	Gigahost AS	not declared	Observed

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.

Registered route objects

25 objects · 25 not announced

Route objects naming AS33891 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.
