Residential LACNIC
Summary
United Telecommunication Services (UTS)
isp legacy
AS11081 belongs to United Telecommunication Services (UTS), the incumbent telecommunications operator of Curaçao in the Dutch Caribbean. LACNIC holds the registration under org handle CW-UTSU-LACNIC with a country code of CW, and the network's reverse DNS resolves under onenet.cw, UTS's long-standing consumer service brand.
What it's used for
Consumer and business internet access across the islands UTS serves. The AS announces 47 IPv4 prefixes (~101,888 addresses) plus one IPv6 /32 (2800:2e0::/32), and RIS observes only 10 neighbours — a small upstream set consistent with an island incumbent that buys international transit and hands it to subscribers, rather than a carrier selling transit onward.
Notable
Every sampled address answers with a mechanical subscriber-pool PTR of the form sub-190-88-128ip5.rev.onenet.cw — the pattern of an access network numbering customer CPE out of large sequential ranges. Combined with the prefix registrations, which sit inside UTS's own LACNIC allocations rather than under unrelated third parties, this is an eyeball network holding and using its own space.
Interesting
The address space is a Caribbean mix rather than a single legacy block: a 190.88.0.0/16 and parts of 190.4.128.0/18 from LACNIC's Latin American ranges, 200.26.192.0/19 and 200.6.60.0/22 from the older 200/8 Latin American space, and ARIN-era 216.152.160.0/20, 198.93.176.0/21 and 206.113.24.0/21 reflecting the region's pre-LACNIC history, when Caribbean operators were numbered out of North American registries.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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 1,773 prefixes, as published 2026-10-13. 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.
