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.

⚠ 1 MOAS prefix — meerdere origin ASNs gedetecteerd

Alle MOAS-anomalieën →

Een voorheen stabiele prefix afkomstig van AS137 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 AS137?

AS137 is een Autonomous System Number toegewezen aan Consortium GARR. 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 AS137 aan?

AS137 kondigt 2.76M IPv4-adressen aan, verdeeld over 83 gerouteerde CIDR prefixes. Het netwerk is geregistreerd in Italy.

Wie beheert AS137?

AS137 wordt beheerd door Consortium GARR. De organisatie is gevestigd in Italy. U kunt alle IP-bereiken en gerelateerde ASNs bekijken op de organisatiepagina.

In welk land is AS137 geregistreerd?

AS137 is geregistreerd in Italy. Dit geeft aan waar de netwerkoperator is gevestigd, hoewel de IP-adressen die het aankondigt wereldwijd gebruikers kunnen bedienen.
