What it's used for

- Announces a single /20,
200.34.112.0/20.
Notable
- Despite the corporate
S.A. de C.V.suffix, CEIT's stated mission is educational: IT instruction, research and technology transfer. TheS.A. de C.V.form is simply how private Mexican educational institutions are usually incorporated, and should not be read as a commercial ISP. - The address space carries no reverse DNS on sampled addresses, so there is no evidence of a subscriber pool.
- Registered through LACNIC, in the Latin American range of legacy space that moved out of ARIN's administration.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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 1,781 prefixes, as published 2026-10-16. 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.
