Domain vs URL

Today we’re diving into the topic of Domain vs URL. They have a lot in common; but there are significant differences.

To illustrate this, we’ll be describing their differences and providing instances in this post.

What is the definition of a domain name?


To begin, a domain name (RFC 1035) is a name for an internet resource. It uses the internet to locate a company or other entity. A domain name is an address that internet users can use to reach your website. Domain names are assigned according to the Domain Name System’s regulations and procedures (DNS protocol). A domain name is any publicly accessible name in the DNS.

A legitimate domain name is required to access any web-based service.,, and are some examples of domain names.

What is a Uniform Resource Locator (URL)?

URL stands for Uniform Resource Locator (RFC 1738). It’s a one-of-a-kind identifier that’s used to find files on the internet. It’s a web address that we utilize to locate a certain network resource.

A URL is made up of several parts:

An URL is always formatted as protocol + subdomain + domain + path + filename.

  • Protocol: normally HTTP or HTTPS
  • Subdomain: generally www
  • Domain name; usually the name of the business or a related keyword 
  • Path + internal page
  • GET Parameters

What is the best way to get just the domain name from the entire URL?

Now that we’ve established that URLs and domain names are not the same thing, mainly because the URL is a string of characters that represents the full address of a web page on the internet, whereas a domain name is just a component of that entire URL, (usually the business name) which is a more user friendly version of the website’s web address. 

Keywords can also be included into the domain name, which can assist you with search engine optimization efforts, but we won’t go into the SEO aspect of that here.

  • For example; if a complete URL is, the domain name is “”

What is the definition of a subdomain?

Simply said, a subdomain, also known as a child domain, is a domain name that has a prefix. It’s essentially a subdomain of the main domain name. is an example of a URL, and “www” is the subdomain.


  • In the event of a given URL, how does the DNS Server work?

DNS resolution is controlled by the domain name.

  • First and foremost, when we request a certain URL from a server, our provider’s local DNS resolver locates its domain name.
  • If a subdomain exists, it will be asked for its IP address.
  • Our browser will then connect to the web server using the IP address and request the material contained within the path.

Let’s look at how DNS works with a URL step by step:

  • First, we’ll attempt to access the following URL:
  • The DNS resolver then looks for the IP address of the subdomain on the domain name
  • It will now create a connection with the web server using its IP address.
  • Finally, once it has established a connection with the webserver, it will request the contents of the URL path and the file /internal/file.html.
