NIC Spider is a powerful program for creating and checking the availability of domain names for your site. Choosing a domain name is a very important procedure because it is the first step in your website promotion. If you select a particular domain, you can easily attract the visitors you need. Using prefixes, the program will generate plenty of domain names mirroring the specificity of your site. The process is very simple - just enter your keywords, select the list of prefixes, specify the top-level domain you need (com, net, org or others) and generate names. Possible name combinations will be created, including names with the keywords. Sets of prefixes available in the distribution kit are compiled after the long collection and analysis of data based on the experience of Internet companies and are considered most successful. The program will check the availability of the names very quickly. Names are checked with the help of multithreaded requests. Each request checks one domain. The number of simultaneous requests can be regulated. The availability of a domain is checked and the main information about it is displayed first. Then the program searches for more detailed information about the domain.
