You saw AS7922 on an IP and want to know what it is. AS7922 is one of Comcast's primary autonomous systems, a large US residential internet provider. Unlike the hosting ASNs, this one is where real users live, and that changes how you should treat it.
What is AS7922?
AS7922 is a main Autonomous System Number operated by Comcast, a major US cable and broadband provider. A route from AS7922 belongs to Comcast's consumer network. For the concept, see what an ASN is.
- ASN: AS7922
- Operator: Comcast Cable Communications
- Type: ISP / residential
- Registry: ARIN (North America)
Who is Comcast?
Comcast (Xfinity) is one of the largest home internet providers in the United States. The IPs under AS7922 are assigned to household broadband connections, so behind them are almost always real people on real devices, not servers.
Why AS7922 traffic is different
AS7922 is a residential network, the opposite of a hosting ASN. Traffic from it carries more trust for fraud scoring, because it represents genuine consumer connections rather than rented servers. A signup from AS7922 is far more likely to be a real customer than one from OVH or AWS.
Should you block AS7922?
No. Blocking a major consumer ISP would turn away large numbers of real customers. The one caveat is residential proxies: a small share of residential IPs are abused to relay traffic, so treat AS7922 as trusted-by-default but still combine it with other signals on high-risk actions.
How to check an IP against AS7922
Look up the IP's ASN with Abstract's free ASN Lookup tool, or call the IP Intelligence API to get the ASN and its ISP type in one request, so you can weight residential traffic appropriately in your risk model. Pair it with the IP Geolocation API for the user's location.
