Comcast

Comcast's Xfinity broadband service is routed under Autonomous System 7922, the largest residential cable ISP network in the United States. Operated by Comcast Cable Communications, it serves tens of millions of customers over hybrid fiber-coaxial and fiber connections. As an eyeball network, AS7922 mostly terminates traffic at homes and businesses rather than providing transit, so it appears as the destination for a large share of consumer internet activity in North America. Registered in the United States, it is among the most populous access networks by subscriber count. As an eyeball network, a matching address usually identifies a home or business broadband line somewhere in Comcast's US footprint.
