AS28548 belongs to Cablevisión, S.A. de C.V.. DB-IP Lite attributes 123,136 IPv4 addresses in 36 ranges and 4 IPv6 ranges to it, all or nearly all of the IPv4 space in Mexico. The number is registered with LACNIC in Mexico on 8 Sept 2008.
Does it publish a geofeed?
Not for the range we sampled (189.217.64.0 – 189.217.111.255): 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 izzi see the wrong city. Customers can ask izzi to publish one; the evidence report drafts that request.
Shared addresses (CGNAT)
izzi 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.
