Reputation · trust score
A transparent 0–100 signal. Every entity starts at a neutral baseline of 65; threat-intel blocklists, exposure, reverse-DNS, routing and allocation each adjust it up or down. Higher is more trustworthy.
- Baseline (neutral) 65

⚠ 11 MOAS prefixes — meerdere origin ASNs gedetecteerd
Alle MOAS-anomalieën →Een voorheen stabiele prefix afkomstig van AS2 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.

Hoeveel IP-adressen kondigt AS2 aan?
AS2 kondigt 78.1K IPv4-adressen aan, verdeeld over 4 gerouteerde CIDR prefixes. Het netwerk is geregistreerd in United States.
Wie beheert AS2?
AS2 wordt beheerd door University of Delaware. De organisatie is gevestigd in United States. U kunt alle IP-bereiken en gerelateerde ASNs bekijken op de organisatiepagina.
In welk land is AS2 geregistreerd?
AS2 is geregistreerd in United States. Dit geeft aan waar de netwerkoperator is gevestigd, hoewel de IP-adressen die het aankondigt wereldwijd gebruikers kunnen bedienen.
