A web domain is essentially the address assigned to your web page; It helps your visitors remember and access your site in an easy way.

New users often confuse web domains with universal resource locators or URLs, and Internet Protocol or IP. This confusion is understandable. It is worth learning the differences between them, since these terms are ubiquitous. It is also useful to be able to use terms correctly when communicating to technicians or other people within a professional organization.

People find web pages in a similar way to the way they use maps to find physical locations. If the Internet is like a phone book and a web page is like a physical building, the URL would be the exact street address of that building. The IP address would be like the car that travels to its destination.


Website Domains & URL’s

The universal resource locator or URL is a set of addresses and contains very detailed information. The domain name is one of the pieces within a URL. It is also the part that is most easily recognized from the whole address. When computer users enter a web address directly in the field at the top of their browser window, a process of locating the requested page begins. For this, the instructions contained within the URL, including the domain name, must correctly point to that location. The IP address is a numeric code that makes it possible.


Domains & IP Addresses

The Internet or IP protocol address is different from a web domain. The IP address is a real set of numeric instructions. Exact information about the address is communicated in a way that is useful to the team, but it does not make sense to humans. The web domains function as a link to the IP address. The links do not contain real information, but point to the place where the IP address information resides. It is convenient to think of IP addresses as the current code and the web domain as a nickname for that code. An IP address is typically recognized as a string of numbers. It could be for example However, human beings can not understand or use that code. To summarize, the web domain is a part of the URL that points to the IP address.

If in any case you still have problems understanding the meaning of web domains below we show you a short video where it is explained in an easy and simple way.


How Do Website Domains Work?

Web domains or domain names work in a similar way to a physical address in the real world. Each part of the domain name provides specific information. These pieces of information allow Internet browsers to locate the web page. The naming system is tightly regulated in order to avoid confusion or duplicate addresses. As demand increased exponentially, a new version of the Internet Protocol or IPv6 was created to expand the number of available domain names.

A common web domain, http://www.google.com is composed of four essential parts:http : // www . google . com is composed of four essential parts:

http: // – HTTP Hypertext Transfer Protocol or in Spanish Hypertext Transfer Protocol is the protocol used in every transaction of the World Wide Web.

www – This is a sub-domain prefix for the World Wide Web. The original use of this prefix was partly accidental and the difficulties of pronunciation raised the interest in the creation of viable alternatives.

  • .Google. – This is a sub-domain
  • .com – This is the top level domain

Many servers use a three-letter name convention for top-level domains and are separated from subdomains by a period. The importance of the top level domain is the most important for new users to understand. Identify the highest part of the naming system used on the Internet. This naming system was originally created to identify countries and organizations, as well as categories.


The most common categories are easily recognizable by new users, and include:

  • .com
  • .org
  • .edu
  • .info
  • .gov


New Domain Names & Their Extensions

With the increasing demand and popularity of web domains that has been given in recent years a new version of the Internet Protocol or IPv6, was created to expand the number of domain names available. Here are some extensions that have been added and are currently available to the general public:

  • .store
  • .Barcelona
  • .Madrid
  • .Paris
  • .football
  • .travels

  • .poker

The country codes are also easily recognizable to new users, because the abbreviations are the same as those used for other purposes. The organization of the domain name hierarchy and the possibility of reserving them for a single purpose has already been subject to several modifications. Discussions and debates about the availability and affordability of domain names can be expected to continue.

Sub-domains are organized to the left of the top-level domain, and this is the part of the domain system that is most recognizable to humans. It is common to see several levels of sub-domains, and some countries developed specific organization conventions to communicate information within their internal name systems.
