Summary
Flow Curaçao
isp residential cable caribbean
AS52233 is operated by Columbus Communications Curacao NV, the telecommunications provider known locally as Flow Curaçao.
What it's used for
- The address space carries residential and business subscriber traffic, with registrants including United Telecommunication Services (UTS) and Columbus Communications Curacao NV.
- The AS announces 50,176 IPv4 addresses across 34 prefixes and 1 IPv6 prefix, while maintaining only 5 observed routing neighbours, a ratio characteristic of an access network rather than a transit provider.
- Traffic consists of cable and DSL subscriber eyeballs, supporting the operator's role as a primary telecommunications provider in the Caribbean region.
Notable
- Registrants for the largest prefixes, such as 190.88.0.0/19 and 190.4.128.0/20, are listed as United Telecommunication Services (UTS), while smaller blocks like 131.221.144.0/22 are registered to Columbus Communications Curacao NV.
- Columbus Communications entered the Curaçao retail market in January 2010 through the acquisition of Curaçao Cable TV NV, and the brand was later unified as Flow following the 2015 acquisition of the Columbus group by Cable & Wireless.
- The inventory includes a mix of large /19 and /20 blocks alongside smaller /22 and /24 segments, reflecting a consolidated estate of acquired and organic address space.

Reputation
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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
