Summary
Uninet / Telmex (Mexico)
isp eyeball backbone
Uninet (UNINET) — the network of Telmex, Mexico's dominant fixed-line telecom, part of América Móvil.
What it's used for
- Fixed broadband and backbone connectivity across Mexico (retailed under the Telmex / Infinitum brand).
Notable
- The largest "eyeball" and backbone network in Mexico by a wide margin.
- Part of América Móvil, the Carlos Slim telecom group that also owns Claro across Latin America.
Interesting
- Telmex's near-ubiquity in Mexican fixed-line service makes Uninet the default path for a large share of the country's internet traffic.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
11 upstream, 112 downstream and 154 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Mobile Cellular carrier. Addresses are shared by many handsets via CGNAT.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 446 networks and 1,852 prefixes, as published 2026-10-27. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
