Summary
Comcast Cable Communications
residential eyeball isp
Comcast's main Autonomous System, serving residential and business broadband
(Xfinity) across large parts of the United States.
What it's used for
- Home and business internet access — this is an "eyeball" network full of end-user connections rather than servers.
- Comcast's own services and its large regional backbone.
Notable
- An IP in AS7922 almost always maps to a subscriber, so it is a normal source for consumer web browsing, gaming, and streaming — not hosting.
- Comcast operates one of the largest broadband footprints in the US and peers and caches heavily to keep popular content local.
Interesting
- Comcast was an early large-scale deployer of IPv6 to residential customers, driven by the exhaustion of IPv4 for its millions of subscribers.
