What is a Domain Name and how it works
What is the Domain Name System?
The Domain Name System (DNS) helps users find their way around the Internet. Every computer on the Internet has a unique address called its “IP address” (Internet Protocol address). Because IP addresses (which are strings of numbers) are hard to remember, the DNS allows a familiar string of letters (the “domain name”) to be used instead. So rather than typing “220.127.116.11” you can type “www.icann.org.”
What’s the difference between registrar and reseller?
The difference between “Domain Name Registrar” and “Domain Name Reseller” is that Domain Name Registrars are accredited and accepted by ICANN for dealing with the Domain Name business in the internet. There is no connection between the Domain Name Reseller and ICANN, Domain Name Resellers are practically reseller’s of the Domain Name Registrar’s and their only connection is between them (the domain name resellers) and the Domain Name Registrars.

What is ICANN?
The Internet Corporation for Assigned Names and Numbers (ICANN) is an internationally organized, non-profit corporation that has responsibility for Internet Protocol (IP) address space allocation, protocol identifier assignment, generic (TLD) and country code (ccTLD) Top-Level Domain name system management, and root server system management functions. These services were originally performed under U.S. Government contract by the Internet Assigned Numbers Authority (IANA) and other entities. ICANN now performs the IANA function.
As a private-public partnership, ICANN is dedicated to preserving the operational stability of the Internet; to promoting competition; to achieving broad representation of global Internet communities; and to developing policy appropriate to its mission through bottom-up, consensus-based processes.
How does ICANN work?
Within ICANN’s structure, governments and international treaty organizations work in partnership with businesses, organizations, and skilled individuals involved in building and sustaining the global Internet. Innovation and continuing growth of the Internet bring forth new challenges for maintaining stability. Working collectively, ICANN’s participants address those issues that directly concern ICANN’s mission of technical coordination. Consistent with the principle of maximum self-regulation in the high-tech economy, ICANN is perhaps the foremost example of collaboration by the various constituents of the Internet community.
ICANN is governed by an internationally diverse Board of Directors overseeing the policy development process. ICANN’s President directs an international staff, working from three continents, who ensure that ICANN meets its operational commitment to the Internet community.
Designed to respond to the demands of rapidly changing technologies and economies, the flexible, readily implemented policy development process originates in the three Supporting Organizations. Advisory Committees from individual user organizations, and technical communities work with the Supporting Organizations to create appropriate and effective policies. Over eighty governments closely advise the Board of Directors via the Governmental Advisory Committee.
What does TLD mean?
TLD stands for top-level domains , generic top-level domains are .com .net.
What is a sub-domain and how does it work?
Sub-domain is a part of the domain name and it is usually used for having a mini-site of a different section for your same business site. For example, yourdomain.com is your domain name and the main site where your faq’s site will be faqs.yourdomain.com , the only purpose of the sub-domain’s is to separate and make easier to remember to the visitor the specific section’s of your web site. Many user confuse the sub-domain www. and consider it as domain. in fact www. (World Wide Web) is a sub-domain.
What does it mean to “register” a domain name?
The Internet domain name system (DNS) consists of a directory, organized hierarchically, of all the domain names and their corresponding computers registered to particular companies and persons using the Internet. When you register a domain name, it will be associated with the computer on the Internet you designate during the period the registration is in effect. From that computer, you can create a web site which will be accessible to Internet users around the world.
