NextraOne provides easy to use domain check tool. You can use this tool to check domain availability or search domains. In the Domain Name Search field, enter the domain name you want to register, and then select the domain name extension from the list or manually enter it. Then hit the search button. If the domain name you are looking for is already registered, you can check alternative options. For example, you can select a .net, .info or .in domain extension, rather than .com.
