Does it publish a geofeed?

Not for the range we sampled (12.1.97.0 – 12.2.11.255): 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 AT&T see the wrong city. Customers can ask AT&T to publish one; the evidence report drafts that request.

Shared addresses (CGNAT)

AT&T 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 83 IPv6 ranges for AS7018, so customers can get IPv6 addresses, which databases place separately from IPv4.
