ASN lookup directory
An autonomous system number (ASN) identifies the network that announces a block of IP addresses via BGP. IPLogs classifies each ASN as ISP, datacenter, CDN, commercial VPN, or cellular, and that classification directly drives the VPN-detection verdict for any IP routed through it. 96 ASNs catalogued below.
