Summary
CICESE
education research legacy
The network of CICESE — the Centro de Investigación Científica y de Educación Superior de Ensenada, a public research centre and graduate school in Ensenada, Baja California, Mexico.
What it's used for
- Campus and research networking for CICESE's institutes and graduate programs, which span oceanography, earth sciences, applied physics, computer science, and experimental biology.
- Announcing the centre's legacy address space, a large allocation by the standards of a single research institution.
Notable
- Research-and-education space, not commercial or eyeball space. Hosts here belong to scientists, students, and instruments.
- CICESE is one of Mexico's major public research centres, and its address holding reflects an era when scientific institutions could obtain generous blocks directly.
Interesting
- The record is administered through LACNIC, having moved out of the original InterNIC-era registry when Latin America took over its own numbering — a common history for low-numbered Latin American ASNs.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
