Domain Names: Introduction
In short, the domain name is a “facade” - call (sequence of words), which enters users in the address bar browsers to visit your site, but which is not a valid address of your site on the Web. Domain names are linked to servers Domain Name Assignment System (DNS), which are used to translate digital addresses (known as IP addresses, or Internet Protocol addresses) in the word. Every site you visit on the Net, except his name is still and digital IP address, which is addressed by this site on the Internet.
Total (generic) Top-Level Domains
Typically, domain names are classified according to their extensions, which represent a domain name identification codes. The three most popular types of Higher Level Domains (TLDs) - This domains, which are not tied to any country:
. COM: Short from. commercial, which means “commercial”. Domain names with the extension. Com on its popularity far exceeds other names and can be purchased by any person or company.
. NET: Short from. network, which translates as “network”. Originally, this domain was created to expand technical websites. But with the expansion of domains can be registered at will.
. ORG: Short from. organization, which means “organization”. Initially, it is intended for non-profit organizations and other organizations that do not use expansion. Com or. Net. Currently, a domain name with the extension. Org can be filed by any person or company.
Domains countries
Domain names can be assigned to the use of country-specific extensions. Each country has its own domain extension; Canada, for example, uses the extension. Ca, Japan -. Jp and Russia -. Ru. In most countries there are special rules, which describe exactly who can register domain names using this extension, and for what purpose, it is therefore important to examine the object before anything done.
Alternative domain names

. aero
. biz
. coop
. info
. mobi
. museum
. name
. pro

Other domains expand
In searching for a suitable domain name, you can find sites that claim to use such as the expansion. Xxx,. Free and. Mp3. This is not a real expansion and they are approved by ICANN, rather, their availability is guaranteed for the user software. Because ICANN is not approved is not one of these extensions and, in addition, users who do not have the appropriate software, can not gain access to sites with names, the data expansion should only be used for some secondary goals.
While expansion. Com,. Net and. Org usually all on hearsay and the mind are not the only expansion that are available for use. From a functional point of view domains countries work as well as any top-level domain, and the expansion of alternative work not worse. Therefore, do not use the top-level domain mediocrity when you can find better with another extension.
