Frequently Asked Questions
What is a domain suffix or TLD?
A domain suffix, also known as a Top-Level Domain (TLD), is the last part of a domain name that appears after the final dot. Examples include .com, .org, .net, and country-specific extensions like .uk or .ca. TLDs help organize the internet's domain name system and indicate the purpose or geographical location of a website.
How many domain suffixes are currently available?
There are over 1,500 active top-level domains currently managed by IANA (Internet Assigned Numbers Authority). This includes generic TLDs like .com, country-code TLDs like .us, sponsored TLDs like .edu, and newer generic TLDs like .blog or .tech. Our tool showcases 40+ popular and commonly used extensions, with the number continuing to grow as new TLDs are approved and delegated.
What's the difference between generic and country-code TLDs?
Generic TLDs (gTLDs) like .com, .org, .net are not associated with any specific country and can be registered by anyone worldwide. Country-code TLDs (ccTLDs) like .us, .uk, .ca represent specific countries or territories and may have registration restrictions based on residency or presence in that country.
Can I register any domain suffix for my website?
Most domain suffixes are available for public registration, but some have restrictions. Sponsored TLDs like .gov (government), .edu (education), and .mil (military) have specific eligibility requirements. Some country-code TLDs also restrict registration to residents or entities within that country. Always check with domain registrars for specific requirements.
How can I use this domain suffix list for my project?
You can search and filter domains by category, copy individual entries or entire lists, and export data in CSV format for external use. This tool is perfect for domain research, web development projects, SEO planning, or educational purposes. The data is sourced directly from IANA's official database.
Is this domain suffix list free to use?
Yes, our domain suffix list tool is completely free to use. You can search, filter, browse, and export domain suffix information without any charges or registration requirements. The data is sourced from the official IANA Root Zone Database and updated regularly to reflect the latest changes.
How often is the domain suffix database updated?
Our domain suffix database is regularly updated to reflect changes in the IANA Root Zone Database. New TLDs are added as they become available, and any status changes to existing domains are reflected in our listings. We recommend checking back periodically for the most current information.
What information is provided for each domain suffix?
For each domain suffix, we provide the TLD extension, category type (generic, country-code, sponsored, etc.), registration status, description or purpose, and where applicable, the country or organization it represents. This comprehensive information helps you make informed decisions about domain selection.
