Domain Name Registrars

A domain name registrar is normally an organization or commercial entity that manages the reservation of Internet domain names. This organisation must be accredited by a generic top-level domain (gTLD) registry and/or a country code top-level domain (ccTLD) registry. Domain name registrar is also responsible for maintenance of domain name registrations in accordance to the guidelines from ICANN.

What is a domain name?


A domain name is used to identify one or more IP addresses. For example, the domain name prabhnoor.com represents one or many IP addresses. It is also used in URLs to identify particular Web pages. For example, in the URL “http://www.prabhnoor.com/index.html”, the domain name is “prabhnoor.com”.

Every domain name has a suffix, that is after the last dot(.) in name,  and this indicates which top level domain (TLD) it belongs to. There are only a limited number of such domains. For example:

  • com – commercial business
  • org – Organizations
  • gov – Government agencies
  • edu – Educational institutions
  • mil – Military
  • net – Network organizations
  • ca – Canada
  • in – India
  • melbourne -Melbourne
  • taxi – Taxi
  • au – Australia

  • Internet is based on IP addresses, not domain names, so every Web server requires a Domain Name System (DNS) server, who translates domain names into IP addresses.

    What is an IP address?


    An Internet Protocol address (IP address) is a numerical name allotted to every device (e.g., PC, printer) taking part in a PC system that uses the Internet Protocol for communication. An IP address serves two central capacities: host or system interface ID and area tending to. A name demonstrates what we look for. An address demonstrates where it is. A course demonstrates how to get there.

    IP addresses have two versions IPv4 (Internet Protocol Version 4) and IPv6(Internet Protocol Version 6). IPv4 use the IP address as a 32 bit number and looks like 127.0.0.45 or similar with four numbers with dot(.) period between each of them. Some others examples can be 182.10.10.56, 180.0.0.12 etc. These numbers  can be any number between 0-255.

    IPv6 uses 128 bits for address and can handle more IP addresses as compare to IPv4. An example of IP address in IPv6 format is  “2002:db7:0:1234:0:456:8:1”.

    The Internet Assigned Numbers Authority (IANA) deals with the IP address space designations comprehensively and delegates five regional Internet registries(RIRs) to dispense IP deliver squares to neighborhood Internet registries (Internet specialist organizations) and different substances.

    I will provide some more information on these topics soon.
