Domain have expanded rapidly and there are numerous Top Level Domains (TLD) and various second level domains. To search a particular domain name is a painful task as we are not sure which is available and which is taken. Domai.nr makes finding domains easy by querying 280 top-level domains and another 2,014 second-level ones for domain hacks, turning real English words into unique and memorable Web addresses.
Apart from searching domain names, Domainr also gives you links to information about international TLDs, so you can find out where they’re based, who controls the domains, and how to register one.
Once you enter any domain name, it searches for all the possible combination that can be got using the name. You can get more details on each domain name (if already taken) by clicking on them. It also gives links to get details on WHOIS information of domains taken.
If any particular domain is available, it tells us which all registrars can help you get the domain name. Domainr does not offer any service to purchase the domain, but if you want to purchase one, click on the registrars link and that will help you to get one.
Overall Domainr is great web tool for domain name search.
