AS worldwide report

An Autonomous System (AS) is a connected group of one or more IP prefixes run by one or more network operators which has a single and clearly defined routing policy. Every network operator must have an officially registered Autonomous System Number (ASN). A unique ASN is allocated to each AS for use in BGP routing. AS numbers are important because the ASN uniquely identifies each network on the Internet. This worldwide ASN report shows detailed information like IPv4 and IPv6 Prefixes, IPv4 and IPv6 Peers, whois information and hosted domains for every ASN. It is grouped by country and sorted by number of ASNs by country.
