⚠ 7 MOAS prefixes — meerdere origin ASNs gedetecteerd

Alle MOAS-anomalieën →

Een voorheen stabiele prefix afkomstig van AS391 wordt nu ook aangekondigd door een andere ASN (MOAS — Multiple-Origin AS), gedetecteerd door onze RIPE RIS-collectoren. Vaak goedaardig (anycast, multi-homing of een recente overdracht) — maar het kan duiden op een route leak of prefix hijack, dus het is de moeite waard om te onderzoeken.

Frequently Asked Questions

Wat is AS391?

AS391 is een Autonomous System Number toegewezen aan Air Force Systems Networking. Een ASN identificeert een netwerk dat een specifieke set IP-adressen beheert en bepaalt hoe verkeer over het internet wordt gerouteerd via BGP (Border Gateway Protocol).

Hoeveel IP-adressen kondigt AS391 aan?

AS391 kondigt 283.6K IPv4-adressen aan, verdeeld over 40 gerouteerde CIDR prefixes. Het netwerk is geregistreerd in United States.

Wie beheert AS391?

AS391 wordt beheerd door Air Force Systems Networking. De organisatie is gevestigd in United States. U kunt alle IP-bereiken en gerelateerde ASNs bekijken op de organisatiepagina.

In welk land is AS391 geregistreerd?

AS391 is geregistreerd in United States. Dit geeft aan waar de netwerkoperator is gevestigd, hoewel de IP-adressen die het aankondigt wereldwijd gebruikers kunnen bedienen.
