Autonomous systems (ASN) directory
An autonomous system (AS) is a large block of IP networks under a single administrative operator: an ISP, a hosting provider or a corporate network. The directory contains 10,000 networks: all 5,114 Russian systems registered in the global routing tables, plus the largest networks in the world. Each network page lists the organization, country, presence cities, prefixes and IP address ranges.
The data is collected from public routing tables (Route Views, RIPE RIS) and refreshed monthly. Our tools work with any address in any network: whois shows registration data, and the subnet calculator breaks a network down for you.
