How to register a domain name for your personal or business use.
The first thing you need to do is determine which domain name registrar you will be using to provide you with registration services. Make sure you use an ICANN accredited registrar for your domain name registration. ICANN provides an extensive list of accredited registrar companies that can act as your registrar. To save you some time and research I would recommend using GoDaddy to register your domain names. GoDaddy is a well established US based company providing domain name registration services along with web hosting and a myriad of other product offerings that can be used with your new domain name.
Now that you have chosen a registrar then the next step is to check the availability of your domain name or website name that you have in mind. Each domain name or website name on the internet is and must be unique. There are no two names that are exactly the same. If you have a domain or website name in mind then you can check domain name availability here. If your name is available and not taken by someone else then you can proceed to register your chosen domain name for a minimum period of 1 year or the maximum period of ten years.
