The Internet has several new extensions for domain names, which work the same as the .com names. One of these is the .cc extension, which is really the country code for the Cocos Islands, but is now being offered for anyone's use.
There are also some other TLDs being used in new ways, such as .tv which is the country code for Tuvalu, a small Pacific Island nation, which has entered into an agreement with dotTV, to market .tv domain names to the general public. If you're business has something to do with television, a .tv name might be good for you.
Similarly .ws (short for "website") is the country code for Samoa, but is now available for use by the public. If your preferred .com domain name is taken, and you can't wait for or afford a .biz name, you might consider .ws instead.
Domain Name Parking
If you're not quite ready to find a web host and set up your web site, or you have a host but no content yet, but you've decided on a great domain name, you can still register that name. Many registrars will provide you with a page for free that you can "park" your domain on, until you get your web site together. You still have to pay the Registrar's fees to park or reserve a domain name.
