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 global AS/BGP report shows detailed information like IPv4 and IPv6 Prefixes, IPv4 and IPv6 Peers, whois information and hosted domains for every ASN.
Showing aggregate number of ASNs, hosted domains, IPv4 addresses and prefixes for each country.
The AS/BGP Report is calculated for every allocated AS number. The report is updated on a weekly basis, last updated on 2022-05-15.
The underlying DNS data is updated every 3 weeks, the Whois data is cached for about one month.
