Understanding Domains

Domain Name has various meanings. It could be the name entered by the users in their address bar of the computer and then looked up in the global Domain Name System-DNS to visit the particular site. All domain names have their own assigned IP address and the DNS translates the IP address into words. It could also be a unique address on the Internet referred to as Internet address. Domain names are also referred to as Uniform Resource Locaters or URLs.

In DNS a label could be the digits, hyphens and each string of letters used between the dots. There are certain rules that are applied emagrecer for these valid labels which have been changed with time. Before labels had to begin with a letter and end with a letter or digit .Any intervening characters may be letters, digits, or hyphens. They must be between 1 and 63 characters long. Now they can begin with a digit and can have internal underscores but no domain name can be all numeric. These rules depend on the domain level. Some top level domains have more rules.

URL and Domain name:
The difference between a URL and a domain name:
URL: http://www.xyz.com/
Domain name: xyz.com

A domain name can have more than one IP address and more than one domain name assigned to an IP address. At the same time one server can have multiple roles, and one role can be applied for multiple servers. One IP address can even be assigned to several servers. The IP address and the server name are interchangeable. This makes it impossible for the server to know which IP address was used. But with the help of HTTP- hypertext transfer protocol, you need to specifically tell the server which domain name is being used. So, one server with one IP address can provide different sites for different domain names.

Say, the server particular server covers all these sites:
xyz.com
xyz.net
xyz.org

When you put a request, then you will get the data corresponding to the host name requested.

Domain Levels:

Top-level domain

The end of all domain names is called top level domain. Say, xyz.edu or xyz.net or xyz.org etc where edu, net and org are all top level domain. This could be a list of generic names or a 2 character territory code like .ac or .ad or .in which are country code top level domains.

Second level domain

Second-level domain names are directly to the left of .com, .net, and the other top-level domains. For example: en.xyz.net where xyz is the second level domain.

Third level domain

The next level i.e. the third-level domains are to the left of a second-level domain. Here en is the third level domain.

Domain Letters

Market value of single- or two-letter .com domains

Only three of the 26 possible single-letter domain letters have ever been registered, all before 1992. The other 23 single-letter .com domains were registered January 1, 1992 by Jon Postel, with the intention to avoid a single company commercially controlling a letter of the Alphabet.

Many but not all .com two-letter domains are among the most valuable domains.

While it is widely believed that the domains business.com and sex.com have been the most valuable domain transactions, prominent two-letter domains have only been sold after nondisclosed transactions handled by specialized broker and law firms.

The value of the LG Group (the South Korean electronics conglomerate formerly known as Lucky Goldstar) purchase of lg.com was never published. LG Group missed the first sale of the domain in 2008 from the original owner the chemical company Lockwood Greene to the British ex- professional footballer AndyBooth, who had used it to launch a footballing website known as LifeGames. They bought it one year later, in 2009, for a significant amount. Following the purchase LG Group changed worldwide marketing to LG.com, which is now their central internet address for all countries. All national LG Country domains like “LG.de” or “LG.com.mx” redirect to “LG.com”.

The value of the initially secret November 2010 Facebook purchase of fb.com was revealed two months later to be $8.5 million.[3]

Fights for Two Letter Domains

Most well known international companies missed the opportunity to register the Internet address that matched their company initials. This is due to the fact that two letter domains were among the very first domains to have been registered, mostly by Internet-savvy technology corporations or by private individuals living in the USA where the Internet was first established.

The French fashion house Louis Vuitton missed the registration of LV.com matching their well known “LV” monogram. In 2004 the address LV.com was for sale by its owner Manifest Information Service but LVMH tried to get it via a domain law suit. As two letters can have many different significations the National Arbitration Forum denied the transfer of the domain. The failed lawsuit was followed by financial negotiations. The British insurance company Liverpool Victoria then became aware of the case; its new president Mike Rogers stepped in and in August 2007 outbid the world’s largest luxury brand.

Controversy

With the 2005 announcement that registration of the remaining single-letter names might become available, some companies have attempted to establish a right to the names by claiming to own trademark rights over single letters used in such a context. U Magazine, a college oriented publication, has gone so far as to re-brand its Web site as “U.com” (with a ™ sign) in online logos and captions—even though it does not operate a web site at that URL. They sent a letter to ICANN attempting to gain priority for registration of this name. Other companies actually use their trademarks in commerce. G.com, which operates a search engine at www.search-g.com, has succeeded in registering its trademark with the United States Patent and Trademark Office(USPTO).
