WHOIS Lookup at DomainTools.com
Examples:
domaintools.com,
whois.sc,
127.0.0.1
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.
Reverse WHOIS
DomainTools.com offers a very powerful tool called Reverse WHOIS making it possible to discover other domains owned
by the same organization, research possible spammers and trademark violators or use for competitive analysis. Enter one or more unique identifiers that appear in a Whois record, and we'll tell
you all the matching domain names (current or historical) with Whois records containing those identifiers. You can also set alerts to watch for future changes using our
Registrant Alert service.
Where is WHOIS.SC?
In 2006, WHOIS.SC (Whois Source) became DomainTools to reflect our expanded toolset for
domain research beyond WHOIS. In addition to a simple availability check and registration information, we now offer
Domain Name Suggestions,
Trademark Monitoring for Brand Protection,
Domains For Sale,
DNS Tools and more.
