Does it publish a geofeed?
Not for the range we sampled (148.252.128.0 – 148.252.191.255): 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 Vodafone UK see the wrong city. Customers can ask Vodafone UK to publish one; the evidence report drafts that request.
Shared addresses (CGNAT)
Vodafone UK 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.
