Summary
Cable & Wireless (Cayman Islands) — Flow
isp legacy
The network of Cable & Wireless (Cayman Islands) Ltd., the incumbent telecom operator of the Cayman Islands, registered under the handle CWCAYMAN from George Town. It trades today as Flow, part of Liberty Latin America.
What it's used for
- Retail broadband, TV, and phone service across the Cayman Islands. Reverse DNS is explicit about it, with subscriber addresses named
…-DYNAMIC.dsl.candw.ky, marking dynamically assigned consumer DSL lines.
Notable
- This is an eyeball network for a small island territory, so addresses on it geolocate to the Cayman Islands with unusual reliability. There is essentially one place for them to be.
- Because the operator is the national incumbent, a large share of all Cayman Islands consumer internet traffic originates from this one AS.
Interesting
- The
candw.kydomain in the reverse DNS outlasted two rebrands. The business went from Cable & Wireless to LIME to Flow, and passed from Cable & Wireless Communications to Liberty Latin America, while the subscriber host names kept the original name.

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: 440 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.
