education university campus

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.

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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
