What is a basic domain list, and how does it differ from a detailed dataset?

Both cover the same 20,850 registered domain names in the .blue zone. A basic list is one domain name per line in a gzip CSV. A detailed dataset adds DNS servers, server IP, hostname, emails, phone numbers, and more. See the dataset format details.

What are active and new domains?

How do I automate daily downloads?

Schedule automatic downloads with the NetAPI. See the API documentation for authentication and endpoints.

Are emails and phone numbers available for every domain?

No. We collect contact details from public websites when available. Many domains have no published email or phone, and we do not guarantee these fields on every row. Do not use the data for unsolicited bulk outreach.

The top-level domain (TLD) .blue refers to the color blue, that is often connected to loyalty, knowledge, and trust. Individuals, companies, and organizations use this domain to develop a distinctive online identity that expresses creativity, tranquility, and stability. A wide range of organizations, including tech companies, designers, and artists, use the .blue domains from all over the world to showcase their products and services and build an impactful online presence.

As part of the new generic top-level domain (gTLD) initiative, which attempts to expand the internet's naming system, the .blue domain was launched in 2014. This domain is administered by Afilias, an American registry business that also manages the .info and .mobi TLDs.

As the current record shows, with just 15,000 registrations, the .blue domain is among the less popular top-level domains. However, the domain name has numerous creative uses; for example, it can be used for personal blogs and environmental protection websites.

Here, you can download the list of .blue domains, as well as .red domain zone lists, .fitness domain zone lists, and others.
