Domain vs Subdomain: What Are the Differences?

A domain is an online address that represents a website. It’s what people type into their web browser to visit your website. A subdomain is a section of your website that has its own web address. It’s like a mini website within your main website.

For example, let’s say your website is www.example.com. You could create a subdomain for your blog at blog.example.com. Anyone who types that address into their web browser would be taken to your blog.

The main difference between a domain and a subdomain is that a subdomain is part of a larger website. It’s like a child website under the parent website. Domains are top-level websites that don’t belong to anyone else.

There are a few other key difference between domains and subdomains:

– Domains are usually shorter and easier to remember than subdomains.

– Subdomains can be used to create a separate website that’s still under the same domain.

– Subdomains are great for SEO because they give you the opportunity to target different keywords.

– Domains are typically more expensive than subdomains.

If you’re just starting out with your own website, then a subdomain is a great option. It’s cheaper and easier to set up than a domain, and you can still use it to create a separate website. Once your website starts getting more traffic, you can always upgrade to a domain.

2. What is a Domain?

A domain is an identification string that defines a realm of administrative autonomy, authority or control within the Internet. Domain names are formed by the rules and procedures of the Domain Name System (DNS).

Any name registered in the DNS is a domain name. Domain names are used in various networking contexts and application-specific naming and addressing purposes. In general, a domain name represents an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, a server computer hosting a web site, or the web site itself or any other service communicated via the Internet. In 2017, 330.6 million domain names had been registered.[1]

A domain name may represent entire collections of such resources or individual instances. Individual Internet host computers use domain names as host identifiers, also called hostnames. The term hostname is also used for the leaf labels in the domain name system, usually without further subordinate domain name space. Hostnames appear as a component in Uniform Resource Locators (URLs) for Internet resources such as web sites (e.g., en.wikipedia.org).

Domain names are also used as simple identification labels to indicate ownership or control of a resource. Such examples are the domain names of the two root servers for the Internet, ns1.example.com and ns2.example.com.

Domain names are also sometimes used in email addresses, for example as the address of an individual user such as john.smith@example.com. This use of domain names as local identification labels is important in many technical standards that define mechanisms and protocols for email address internationalization and international domain name resolution.

The process of registering a domain name generally involves a central registry operator, which performs registry services on behalf of registrars.

3. What is a Subdomain?

A subdomain is a domain that is part of a larger domain. Subdomains are created to organize and navigate to different sections of a website. For example, on a website with a main domain of example.com, a subdomain could be blog.example.com, which would take users to a blog section of the website.

Subdomains can be used for organizational purposes, or for creating separate websites that are still connected to the main domain. For example, a company might use a subdomain to create a website for their employees, or to create a customer portal.

Subdomains are created by adding a prefix to the main domain. For example, to create the subdomain blog.example.com, the prefix “blog” is added to the main domain “example.com”.

Once a subdomain is created, it can be used like any other domain. That means it can have its own website, email address, and even its own DNS records.

4. The Difference Between a Domain and a Subdomain

A domain is an online address that represents a website or email. Subdomains are a subset of the domain that you can use to organize your website into sections. For example, you could have a blog.example.com subdomain for your blog, and a shop.example.com subdomain for your online store.

The main difference between a domain and a subdomain is that a subdomain is a part of a larger domain. Domains are top-level while subdomains are subordinate. This relationship is represented by the fact that subdomains have an additional label to the left of the root domain.

For example, in the domain name www.example.com, the root domain is “example.com”. The “www” subdomain is subordinate to the root domain. In the domain name blog.example.com, the root domain is still “example.com”, but the “blog” subdomain is subordinate to the root domain.

The different levels of the domain name system (DNS) are:

– Top-Level Domains (TLDs): These are the highest level domains, such as “.com” or “.org”.

– Second-Level Domains (SLDs): These are the domains that are beneath the TLDs, such as “example.com”

– Subdomains: These are subordinate domains, such as “blog.example.com”.

Each level of the domain name system can be further divided into sublevels. For example, the “.com” TLD can be divided into “.com”, “.net”, and “.org”. The “example.com” SLD can be divided into “example.com”, “example.net”, and “example.org”.

The main advantage of using subdomains is that they can help you to organize your website into different sections. This can be helpful for both visitors and search engines.

For example, if you have a blog on your website, you could use a subdomain to keep the blog separate from the rest of your website. This would make it easier for visitors to find the blog, and it would also help search engines

5. How to Choose Between a Domain and a Subdomain

When it comes to setting up a website, one of the first decisions you’ll need to make is whether to use a domain or a subdomain. Both have their advantages and disadvantages, so it’s important to understand the differences before making a decision.

A domain is the main address of a website. For example, the domain for Google is google.com. A subdomain is a section of a main domain. For example, the subdomain for Google Maps is maps.google.com.

The main advantage of using a domain is that it’s easier to remember than a subdomain. This is because the domain is the main address of the website, so it’s less likely to be forgotten. Additionally, domains are generally more expensive than subdomains, so they tend to look more professional.

The main advantage of using a subdomain is that it’s easier to set up. This is because you don’t have to purchase a new domain, you can simply create a subdomain off of an existing domain. Additionally, subdomains are often cheaper than domains, so they can be a good option for those on a budget.

So, which should you choose? Ultimately, it depends on your needs. If you want a simple, easy-to-remember address for your website, a domain is the way to go. If you’re on a tight budget or you need a quick and easy way to set up your website, a subdomain is a good option.
