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
- Active-threat / abuse risk −12
- Enterprise allocation +4

⚠ 15 MOAS prefixes — meerdere origin ASNs gedetecteerd
Alle MOAS-anomalieën →Een voorheen stabiele prefix afkomstig van AS1637 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 AS1637?
AS1637 is een Autonomous System Number toegewezen aan Headquarters, USAISC. 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 AS1637 aan?
AS1637 kondigt 202.0K IPv4-adressen aan, verdeeld over 13 gerouteerde CIDR prefixes. Het netwerk is geregistreerd in United States.
Wie beheert AS1637?
AS1637 wordt beheerd door Headquarters, USAISC. De organisatie is gevestigd in United States. U kunt alle IP-bereiken en gerelateerde ASNs bekijken op de organisatiepagina.
In welk land is AS1637 geregistreerd?
AS1637 is geregistreerd in United States. Dit geeft aan waar de netwerkoperator is gevestigd, hoewel de IP-adressen die het aankondigt wereldwijd gebruikers kunnen bedienen.
