AS10436 Instituto Tecnologico y de Estudios Superiores de Monterrey

The Autonomous System of the **Instituto Tecnológico y de Estudios Superiores de

Monterrey** — Tec de Monterrey, a large private Mexican university with campuses

across the country and its main site in Monterrey, Nuevo León.

What it's used for

• Campus connectivity for the Tec system: teaching and administrative buildings, research groups, student networks and the university's public-facing services, spread across its multi-campus footprint.

Notable

• Education, and an end-site rather than any kind of provider. RIS sees 16 IPv4 prefixes carrying about 71,680 addresses, with just 1 observed BGP neighbour. A single neighbour means a single upstream and no downstream customers at all — the network buys reachability and resells none of it. That alone rules out transit, and the address volume is far too large and too static to read as hosting.
• The prefixes are the second confirmation. Everything originates from two legacy university-era blocks, 148.241.0.0/16 and 132.254.0.0/16, carved into /18s through /22s. Deaggregating your own two contiguous blocks per-campus is what a multi-site institution does for internal traffic engineering; it is the opposite of the scattered, multi-RIR, third-party-registered pattern that marks brokered address space.

Interesting

• The word Instituto in a legal name is not by itself evidence of an education network — plenty of commercial firms carry it. What settles this one is the combination: a 132.x legacy block from the early academic allocations, a single upstream, and address space sized for a campus population rather than a customer base.
