Learn What Domain Names Are And How They Differ From A URL

By Dean Smith


Simply put, domain names are realm designations or identification labels that describe a territory of administrative control, independence, or power in the world of internet. They also identify an IP, internet protocol, resource like a web site. It is important to understand the difference between a URL, Uniform Resource Identifiers, and a realm designation.

The DNS, or Domain Name System, dictates the procedures and rules by which a designation is created. The designations are organized in subordinate order in the DNS with the first level being the top level or TLDs, top level domains. These include generic top level domain names or gTLD that use com, org, and net. They also include ccTLD names, or country code top level domains.

The second and third level are next in line and are typically used by people who want to connect local networks on the internet, create a public access resource, or operate a web site. The realm designations are managed by registrars who charge for their services.

Many people will set up a blog or attempt to design a web site without completely understanding domains and URLs. With the number of sites available to help complete these tasks not many people take the time to learn what the connection is and how they operate. In fact many individuals think that they are the same as a URL. The confusion is understandable since the two work together to get people to the resource they have searched.

However, they are a hostname used to identify the host and are part of a URL. They indicate the ownership of a specific resource. The URL is a numerical sequence that takes an individual to the specific site. An example of a realm designation that is part of a URL for a web site will look similar to www.mywebsite.com.

The name is actually a label used to indicate ownership of a specific resource. They offer a simple way of recognizing or memorizing the designations to all internet sources. The tags or names are called domains, and the domain owners are the registrants. When an individual registers a name, it gives them the right of sole use, however it is not a legal right of ownership.

It is easy to learn what the purpose of domain names is and how they relate to URLs. Remember that hostnames are domains that are a part of the URL which is the numerical address to a specific site. URL directs to the site and the name is indicative of ownership.
