The Connection dataset describes how each IP range connects to the Internet: the AS number and organization announcing it, the exact BGP route (prefix) it is announced under and the connection type of the network.
It is the offline counterpart of the connection object returned by the Ipregistry API and a building block for traffic classification, fraud scoring and network analytics.
