— Why we do not provide daily updates for .uk zone?
— Country-code registars never open their zone files to the public. The only way to discover domains in country-code zones is to do a massive recursive scan of all known websites. That's what we're doing. We use a massive cluster of servers and crawl the Web, then we check and clean the resulting lists. We know of millions of CCTLD-domains in hundreds of zones (and currently know of 4,433,198 domains in .uk zone), but we do not cover 100% of them (some of the smaller websites simply do not have any inbound links and that means that our crawlers cannot find them). Meanwhile we regularly add new domains to this list (1 time / month).

.UK is the ccTLD, or Internet country code top-level domain for Northern Ireland and the United Kingdom of Great Britain. Curated by its registrar Nominet UK, the domain was founded in May 1996 by Dr. Willie Black and five others as a response to its predecessor, the "Naming Committee," not being able to handle the number of registrations being sought under the .uk domain. Now with over 10 million registrations, it is currently the fifth-most commonly used top-level domain zone in the world (following .com, .cn, .de, and .net).

Nominet is a non-profit company funded by shareholders who serve as members but do not possess the right to participate in the profits of the company. Because Nominet was one of the first professional ccTLD operators, it now serves as a model for other operators around the world. .UK has also expanded to contain various second-level domains, such as, which refers to commercial and general content,, which refers to government content, and many others.
