A domain name is the combination of words, phrases, abbreviations, or characters that, together with a domain extension, are used to create your Website address and/or Email address. In other words, it's the name by which you or your organization are identified on the Internet. For companies in particular, your choice of domain name can have a measurable impact on your online image and influence, so choosing wisely is important. Additionally, since there is very little regulation controlling who can have a domain name, the name you want may already be registered by someone else. To find the right domain name, the list below contains the most popular sites for identifying, buying, registering, and trading domain names. Most also offer Web hosting services so you can put your domain name to use via a Website.
