AS6639 CWCAYMAN

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.ky domain 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.
