Summary
Cable & Wireless Jamaica
residential broadband dsl business-internet flow caribbean
CWJ-1 is Cable & Wireless Jamaica, the island's incumbent telecommunications operator, which sells consumer and business internet under the Flow brand as part of Cable & Wireless Communications (now Liberty Caribbean, under Liberty Latin America).
What it's used for
Fixed internet access in Jamaica. The space carries a mix of residential broadband lines, dedicated business circuits, and hosted or on-premises servers belonging to Jamaican companies that buy connectivity from C&W.
Notable
The reverse DNS reads like an incumbent's customer estate, which is exactly what settles the kind. Three distinct patterns appear in the sample. First, subscriber lines: 5-174-131-208-br1-STATIC-dsl.cwjamaica.com — DSL access, aggregated on a broadband router, with a static address. Second, dedicated internet access: 5-32-163-208-STATIC-dia.cwjamaica.com, where dia is the industry abbreviation for a leased business circuit. Third, the customers themselves: mail.anngel.com and wisynco005.wisynco.com — Wisynco is a large Jamaican beverage and distribution group. Customer-branded PTRs inside carrier space mean the operator delegated the reverse zone to the businesses it serves.
So this is an eyeball/access network, not a carrier. RIS observes 69 announced IPv4 prefixes carrying 27,136 addresses, headed by 208.163.32.0/20, against just 2 BGP neighbours. Two adjacencies is decisive: a transit business is defined by peering breadth, and this AS has essentially none. It is an access network reached through group upstreams.
Interesting
The dsl versus dia split in the naming is a useful reminder that a technology label in a hostname describes the access method, not the customer — STATIC-dsl here sits alongside enterprise DIA in the same zone.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
