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

0 objects · 0 not announced

Route objects naming AS24354 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.

No route objects name this AS as origin.

IRR

AS-sets

The as-set is what upstreams expand to build this network's customer filter. Sets that list AS24354 directly show who expects to carry it.

AS-set	Where	Relationship
`AS23911:AS-CUSTOMERS-V6`	APNIC	Lists AS24354 as a direct member
`AS4538:AS-CUSTOMERS`	APNIC	Lists AS24354 as a direct member
`AS4538:AS-CUSTOMERS-V6`	APNIC	Lists AS24354 as a direct member
