Unclassified LACNIC NSP
Summary
Sencinet LATAM Argentina
enterprise legacy
Sencinet LATAM Argentina SA is the Argentine arm of Sencinet, the company formed in 2020 when CIH Telecommunications Americas bought British Telecom's domestic Latin American operations. The AS is still labelled BT LatAm in some peering records.
What it's used for
- Corporate and government connectivity in Argentina: managed WAN and MPLS, satellite links, data-centre services and enterprise internet access, sold to businesses rather than to households.
- The inventory is around 45,000 IPv4 addresses across roughly 110 prefixes, almost all of it in
200.47.0.0/16and200.89.0.0/16from LACNIC, plus an IPv6/32.
Notable
- Reverse DNS is uniform and generic —
200-47-NNN-N.sencinet.comandlineN.sencinet.com— with none of thepppoe-,dsl-orcable-markers that identify a consumer access network. This is a B2B carrier's address space, so it should not be treated as eyeball space despite its size. - The ASN was registered in February 1997, so the low number is a genuine early Argentine allocation that has survived several changes of owner: the network passed through BT's Latin American business before the 2020 sale.
Interesting
- The name on the AS has changed more than once while the address space stayed put — a good reminder that a corporate rebrand does not change what the prefixes actually carry.

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 1,771 prefixes, as published 2026-10-15. 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.
