Where you Buying Domain?
Domains are administered and sold by domain registrars, which are companies certified by the Internet Corporation for Assigned Names and Numbers (ICANN). The first domain registrar was Network Solutions (www.networksolutions.com), and that company is still doing business. Another popular one is Register.com (www.register.com), which benefits from a great domain name. I have used both those registrars as well as Go Daddy (www.godaddy.com).
Dozens of others exist. A domain is just a name paired with a top-level domain extension (such as .com, .net, .biz, or .org, or one of many other approved extensions). When a name is available, ownership must be renewed every year or less frequently if you buy a longer term. Unrenewed domain names fall into the public market. Many registrars sell domains at a lower annual cost and offer discounts for long-term purchases or bulk purchases of multiple domains. Domains may be purchased in the private market and transferred from one owner to another at a negotiated price.
When you buy a domain, you own only the specific Web address, not the name generally. For example, if your domain is www.greatdomain.com, you own greatdomain.com, but do not own greatdomain.net or the term greatdomain paired with any other extension. If you want to lock down the domain term to prevent copycat site names, you must buy all the extensions individually (if they are available). You don’t need a Web host to buy a domain name, but you may get your Web hosting deal in place before shopping for a domain if you want. In other words, it doesn’t matter which you get first.
