AS10479 Instituto Tecnologico y de Estudios Superiores de Monterrey
Education RIPE
Summary
Tecnológico de Monterrey (ITESM)
AS10479 belongs to the Instituto Tecnológico y de Estudios Superiores de Monterrey, universally known as Tec de Monterrey — a private research university founded in 1943 and today one of Latin America's largest, with roughly 35 campuses spread across 25 Mexican cities.
What it's used for
Carrying the university's own campus networks. RIS sees 36 announced IPv4 prefixes totalling 9,216 addresses, essentially all of them /24s drawn from LACNIC's 200.34/16 Mexican range: 200.34.96.0/24 through 200.34.111.0/24, then 200.34.152.0/24, 200.34.176.0/24–200.34.191.0/24 and neighbours. No IPv6 is announced.
Notable
This is genuinely an education network, and the routing pattern is the reason to believe it rather than the word Instituto in the name — a legal name proves nothing on its own. What proves it is the shape: three dozen separate /24s, sitting in clumps of consecutive blocks, announced individually rather than aggregated. That is a multi-campus institution that acquired address space campus by campus over decades and never renumbered, each site getting its own /24. A hosting provider would aggregate; an enterprise would hold contiguous space.
Only 1 observed neighbour appears in RIS. Tec de Monterrey buys transit and does not sell it, so the AS has no wholesale role — everything inside it is students, faculty, labs and administrative systems.
Interesting
At around 9,200 routable addresses spread over 35 campuses, the university clearly runs its user population behind NAT; the public space is for servers and edge infrastructure, not per-student addressing.

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: 442 networks and 1,771 prefixes, as published 2026-10-15. 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.
