Summary
ETECSA — IXP Cuba (NAP-ETECSA)
isp transit legacy
AS11960 is held by Empresa de Telecomunicaciones de Cuba S.A. (ETECSA), the Cuban state telecoms monopoly, and is the AS attached to IXP Cuba / NAP-ETECSA — the country's national exchange point. LACNIC lists it in Havana with contacts at nap@etecsa.cu.
What it's used for
Interconnection infrastructure, not customer service. RIS sees a single IPv4 /24 (200.0.16.0/24, 256 addresses) and one IPv6 /32, through four observed neighbours. ETECSA's subscriber traffic lives on its main AS, AS27725; this number carries the exchange and gateway function instead. The four neighbours are the point of the whole thing — a tiny address footprint attached to a disproportionate role in how a country reaches the rest of the internet.
Notable
This is deliberately not classified as hosting, eyeball or transit product space. An exchange-point AS holds peering-fabric and NAP infrastructure addresses; classifying 200.0.16.0/24 as though it served end users or servers would mislabel every address in it. RDAP on the prefix failed during collection, which is a gap in the evidence and not a clearance.
Interesting
Cuba's connectivity is unusually concentrated: one state carrier, one exchange, and a small number of international links. That makes an AS this small structurally significant in a way its 256 addresses cannot convey — the size of the block says nothing about the importance of the function.

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 2026-10-10, 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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
