AS11081 United Telecommunication Services UTS

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.
