Domain names serve as a unique identifier on the internet, that classify Internet Protocol (IP). For websites they act as an address or a location as well as a tool for naming and branding a company’s internet identity. Domain names are formed by the rules and procedures of the Domain Name System (DNS).
Domain names can be searched and purchased on domain registrars such as godaddy.com, for more information about setting up a domain name refer to Set Up a Custom Domain.
Magento Go allows you to launch a store very quickly – without even having to register a domain. With Magento Go, your store can be accessed by going to yourstorename.gostorego.com.
Alternatively, most merchants want to use their own domain name (your own .com address). If you already have a domain name registered, or are thinking about purchasing a domain name for your Magento Go store rest assured that it is not difficult to set up.
