About .cu
Cuba's country code top-level domain, .cu, represents the Caribbean island nation in the global domain name system. Administered by the University of Informatics Sciences (UCI) under the oversight of the Cuban state, .cu is heavily regulated and predominantly used by government entities, state-run enterprises, and approved academic institutions. Cuba's internet access has historically been restricted, which has limited the breadth of the .cu namespace compared to other ccTLDs.
The .cu TLD was delegated in 1992 and operates under strict government control consistent with Cuba's broader communications policies. Foreign registrations and private sector use are highly limited. As Cuba has gradually expanded internet access in recent years, the .cu domain space has begun to grow, though it remains one of the more tightly managed ccTLDs in the world. Second-level domains such as .co.cu and .com.cu are used for commercial entities.

The .cu dataset
Everything we have on 1,329 active .cu domains in one downloadable file — fresh export every day.
Buy a dataset to download .cu
The full .cu slice (7.8 KB JSONL, fresh daily exports) lives inside each dataset. Get one from €29 to €599 per month and download immediately.
How to download the .cu domain list
The complete .cu domain list is available as one structured file. Every entry in the list is a single registered domain exported with its full record, so you can work it all offline instead of crawling it yourself.
Pick the dataset that fits your use case, then download the .cu list in JSONL (zstd-compressed) — the very same list that powers our API. A free sample of the list is available before you pay, and you can re-download the latest export any time during your access month.
Each .cu list includes, for every domain:
- DNS, RDAP and WHOIS records — registrar and dates across the full list.
- Detected technologies for each site in the list.
- Hosting IP, country and PageRank / Harmonic ranking.
- A daily-refreshed export, so the list you receive is never stale.
