Summary
Red CENIAInternet (CENIAI)
isp government research legacy
Red CENIAInternet is the network of CENIAI (Centro Nacional de Intercambio Automatizado de Información) in Havana, the organisation that administered Cuba's first Internet connectivity and still holds the country's original address allocation.
What it's used for
The routing is unusually clean for a network this old: RIS observes exactly one IPv4 prefix carrying 65,536 addresses — 169.158.0.0/16, announced whole, with no deaggregation at all — plus a single IPv6 prefix, 2001:1340::/32. That /16 is Cuba's founding block, delegated to CENIAI in the mid-1990s, and it is still announced as one route thirty years later.
One observed BGP neighbour tells you this is not a carrier. CENIAI sits behind a single upstream and provides connectivity and hosting to Cuban institutions — scientific, academic, state and enterprise organisations — rather than selling transit onward. Cuba's mass-market and mobile subscribers ride ETECSA's networks, not this one, so the /16 is best read as institutional space: servers, mail, and organisational access rather than consumer eyeballs.
Notable
A country's entire early Internet presence in a single unsplit /16, behind a single peer, is a rare shape today. It reflects a network built when Cuba's connectivity was a single satellite-era link into a state research institution, and one that has never had commercial reasons to fragment.
Interesting
The block predates the RIR system's Latin American arm — it was assigned directly, before LACNIC existed, which is why a Cuban network sits in what looks like North American address space.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
