Networks and maps

The networks and prefixes this site keeps maps for. Everything else works too: type any prefix, IP address or AS number into the search box and the map is drawn from live data. This list is only the part worth browsing.

A network's page lists the prefixes it announces and its upstreams, and links to a map of each. A map shows the AS paths that RIPE RIS collectors see towards one prefix. If you have not read one before, how to read a BGP map explains the boxes and arrows.

A hand-kept list of big transit providers that are not transit-free, the blue boxes on a map.
