Summary
Instituto Tecnologico y de Estudios Superiores de Monterrey (Tec de Monterrey)
education university research legacy
AS11136 belongs to the Instituto Tecnológico y de Estudios Superiores de Monterrey — Tec de Monterrey — one of Mexico's largest private universities, with a multi-campus system headquartered in Monterrey, Nuevo León.
What it's used for
Campus networking for a university system. RIS observes 10 IPv4 prefixes carrying about 20,736 addresses, no IPv6, and a single BGP neighbour. One upstream and roughly a /17 of aggregate space is the classic shape of an institutional edge network: the AS exists so the university can hold and advertise its own address space, not to move anyone else's traffic. The size fits a campus estate — labs, faculty and administrative networks, student housing and wireless, plus the institution's own public-facing services.
Notable
The address space splits into two eras. The 132.254.0.0/16 blocks are legacy pre-CIDR class-B space, and the RDAP registrant for the announced pieces resolves to the parent 132.254.0.0 - 132.254.255.255 range rather than to separate third parties — the university is announcing sub-blocks of its own /16. The 200.36.224.0/19 group is LACNIC-region space, consistent with a Mexican allocation made after the region got its own registry. Both are first-party; there is no sign of foreign or leased blocks riding on this AS.
Interesting
Several of the RDAP lookups in the evidence pack failed rather than returning a registrant, so those prefixes are simply unverified — not evidence of anything. Reverse DNS returned nothing on the sampled addresses, which is a sample and no more; nothing about the zone's delegation should be read into it.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
