AS3839 ERX-CHULANET Chulalongkorn University

Every prefix observed with AS3839 as its origin, checked against RPKI and the IRR. Problems sort first.

Signed statements by address holders that AS3839 may originate these prefixes, up to the maximum length shown.

ROA-based and RPKI-valid-only prefix lists for routers are on asn.ipinfo.app.

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.

Route objects naming AS3839 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.

Showing 200 of 523.

The as-set is what upstreams expand to build this network's customer filter. Sets that list AS3839 directly show who expects to carry it.
