Availability Check
DomainTools.com supports more Top Level Domains (TLDs) than any other Whois service. In addition to the popular Generic TLDs like .COM, .NET, .ORG, etc., we also support hundreds of Country Code TLDs (ccTLDs). We offer a basic DNS check for those registries which don’t provide standard Whois access and our site is IDN friendly, making it easy to find available domains in other languages.
Whois and Hosting History
There are many websites offering a basic Whois lookup service, but our site offers extensive historical information including Whois, IP Address (website hosting), Name Server, Registrar and Screenshot history to help provide a complete view of a domain name’s life cycle. When buying a domain from someone you may not know or trust, make sure you protect yourself by researching the domain’s history.
