Does it publish a geofeed?

Not for the range we sampled (24.0.0.0 – 24.23.255.255): its registry record, and the record above it, link no RFC 8805 geofeed (checked 2 Nov 2026). Without one, location databases have to estimate where these addresses are used, which is a common reason customers of Xfinity (Comcast) see the wrong city. Customers can ask Xfinity (Comcast) to publish one; the evidence report drafts that request.

Shared addresses (CGNAT)

Xfinity (Comcast) hasn’t been documented as using carrier-grade NAT in a source we could check. To see whether your own connection is behind it, compare your router’s address on the CGNAT check.

IPv6

DB-IP lists 941 IPv6 ranges for AS7922, so customers can get IPv6 addresses, which databases place separately from IPv4.
