ASN Directory
Every autonomous system that announces significant IPv4 space or sells infrastructure — 6,158 of them. Built from the public global routing table, refreshed daily. Showing the 500 largest by announced address space.
An AS number says who announces an address, not whether that address is risky. Maskbreak deliberately keeps routing data out of its risk score — see any AS page for why.

Looking for a specific address?
The directory answers "who announces this range." To find out whether a particular address is currently a VPN exit, a proxy, or a Tor node, check it directly with the free lookup tool — those are live properties of a connection, not properties of the AS.
