The AS dataset covers all allocated Autonomous System Numbers. Each ASN comes with the operating organization, its website domain, a classification of the network, the country of registration and the regional Internet registry that allocated it.
Keyed by ASN rather than IP range, it is the reference companion for BGP tooling, peering analysis and enriching any data source that already carries AS numbers.
