DOMAIN INFORMATION

A domain name is a company's unique identifier on the Internet. The same domain name can be used with a company's Web address and their email addresses.

The format for a professional Web address is usually "www.company.com" while an email address is generally myname@company.com. A Web address does not have to begin with "www" but it has become standard over time and is easy to remember.

In this digital age it is not a good idea to use another company's domain name in your Internet dealings. For example, the email addresses company@hotmail.com or company@yahoo.com do not properly identify your business and using those domains implies your company might not be Net savvy. Similarly, it looks unprofessional to have your Web address in the form: http://www.myisp.com/mycompany/.

Domain names are part of the Internet's domain name system (DNS), which allows "user-friendly" names to replace the more difficult numerical IP addresses, such as "206.168.98.225", that computers actually use to direct information to other computers.

Domains must be registered with an official Internet standards body. For example, in the United States, Network Solutions keeps a registry of the domain names. Another standards body (in the United States it's Internet Assigned Numbers Authority [IANA] ) keeps a database of the IP addresses.

Each domain name has two main parts, in the following format:

TOP LEVEL DOMAIN NAMES

The original purpose of top level domains was to help define the type of enterprise named in the second level.  Three  top level domain names -- .com, .net, .org -- are designated as unrestricted, which allowed anyone to apply for a name using that top level domain suffix. Use of  the remaining five top level names was restricted to specific situations.

Unrestricted top level domain names. The explosion of the Internet, the resulting scarcity of names, and marketing strategies have resulted in the three unrestricted top level domains losing their original distinctions.  Even restricted top level domains are changing to accommodate the increased demand.  This pressure for names has led to discussions of new top level domains, but the Internet's overseeing standards body --  The Internet Corporation for Assigned Names and Numbers (ICANN) -- has not yet released a formal list.

Here's a list of the original three top level domain names:

• .com, an unrestricted domain designed for companies or commercial enterprises.
• .net,  an unrestricted domain intended  for network providers and their computers
• .org,  an unrestricted  miscellaneous category for organizations that didn't fit anywhere else, mostly used by not-for-profit organizations.

Restricted top level domain names. Even though the Internet is a worldwide network, some of the restricted domain names (e.g., .mil) were reserved for specific U.S. use. These special U.S. names date back to origins of the Internet as a U.S. military project sponsored by the Defense Advanced Research Projects Agency.

Here's the original list of top level domains:

• .int , a restricted domain name for international databases and organizations established by international treaties
• .gov, a restricted domain name  intended for any kind of government agency or office but which is now only for U.S. federal government agencies.  State and local agencies are being registered under the country domain of .us (see "International naming conventions, below)
• .mil,  a restricted domain name for use only by the U.S. military
• .edu, a restricted domain name originally intended for all educational institutions but now limited to four-year colleges and universities.

International naming conventions. In addition to the seven listed above there is one further category of domain names: country codes. These codes distinctly identify the nation in which the domain name was registered.

Some country code top level domains, or ccTLDs, have certain criteria for persons or entities that wish to register, such as a residence requirement. For example, the .au top level domain name belongs to Australia and is a ccTLD. The Australian registry requires that a domain name must be part of an Australian registered business or company name. Most ccTLDs have no restrictions.

Here's a list of the country codes currently in use:

SECOND LEVEL DOMAIN NAMES

Second level domain names are almost completely unrestricted. That's why they're so important in marketing your site. There are three rules you must follow when naming your site:

• All characters must be alphanumeric, meaning letters and numbers, with the exception of a hyphen ("-").
• The hyphen cannot be used at the beginning or the end of the domain name.
• The second level domain name has a maximum character length of 67.

More information about rules for specific domains can be found in our Domain Name Rules section.

DOMAIN NAMES AS AN INVESTMENT

Today .com and .net names have considerable resale value since they are business investments that can identify your company on the Internet practically forever. And most companies over time will conduct a considerable portion of their business over the Net, if not all of it. The most important aspect of generating new business and conducting business on the Internet is a domain name that is easy to remember for your customers and prospective customers. Also, an important consideration is to have relevant "key words" as part of your domain name that will enable customers to find your site easily through Web based search engines.

Many companies feel that they are stuck with a marginal name that they have been using for some time. However, you should realize that you can easily have multiple URL addresses (which include your domain name) point to the very same Web site. This will allow you to keep your legacy domain name and to have multiple new ebusiness names to conduct commerce with and list in the search engines.

POSSIBLE NEW TOP LEVEL DOMAINS

You may have heard about the proposal to create new top level names like .web, .store and .firm. This idea has been around for a long time however there are already many other top level domains around the world that consist of country codes instead of .com or .net - like .uk, .au, .to, .cc, .ca, etc. Despite the existence of alternative top level names the majority of the business world is buying names and branding companies with .com and .net extensions and abandoning other possibilities. This makes sense because presently the highest trafficked sites and the easiest sites to remember all use .com and .net. Another relevant point is that many web browsers do automatic lookups of .com addresses but no others.

We expect that names with .com and .net will store their value practically forever and only lower profile companies and sites will experiment with alternative top level domains.

RESERVE YOUR DOMAIN TODAY BEFORE SOMEBODY ELSE DOES!

In our opinion, investing a few dollars to permanently control prominent sounding Internet brand names is a deal that you would be foolish to wait on. Procrastinating risks that your competitors beat you to the names that you like or that their prices continue to rise.
