A Bit of Background Context

Before we head to the details of the main question, “Which domain is reserved for the military in the U.S?” Let’s briefly go through a bit of background context.

1. What Is a Domain Name?

A domain name is what you put into the search bar when you access the Internet to navigate to a page. It ends with domain name extensions, like “.com”. “.net”, “.edu”, “.org”, and “.gov”. These are called TLDs or Top Level Domains.

To reserve a domain name, one must register it and renew it each year. The fees to do so vary but renewing fees are typically from $12. Specialty domain names, though, can cost hundreds of dollars. The registration process is straightforward and usually done through registrars.

Some domains are strictly reserved. For example, in the U.S, “.edu” is only for accredited universities and “.gov” is only for government organizations. Another one is “.mill”, which is for the U.S military — and is the subject of this article.

  • Note: The .mil domain extension is often mistaken as a military IP address, but the latter is something different. You can search for more information about IP addresses (separately) if you are unfamiliar with them.

2. What Is “.mil”?

The .mil address is a domain name.

It is a sponsored top-level (sTLD) in the Internet’s Domain Name System. ‘.mil’ is reserved for the United States Department of Defense, its subsidiaries, and its affiliated organizations.

It was introduced 37 years ago on January 1, 1985. Its registry is the Defense Information System Agency and as an sTLD, it is sponsored by the DoD Network Information Center.

3. What Does “.mil” Mean?

Mil is not just three randomly selected letters. The extension is actually taken from the word “military.” It is the first three letters.

4. What Is Special About “.mil”?

It is the only top-level domain for the military. Hence, the United States is the only country with a domain as such. Other countries use second-level domains for their militaries. For example, the UK uses mod.uk for its Ministry of Defense.

5. What Are the Military’s Websites With “.mil”

The military’s service branches all have their own website and the .mil domain.

So, for example, the Army’s domain is .mil as well.

Here is the full list:

  • The U.S Army’s website is https://www.army.mil/
  • The U.S Marine Corps’ website is https://www.marines.mil/
  • The U.S Navy’s website is https://www.navy.mil/
  • The U.S Air Force’s website is https://www.airforce.com/
  • The U.S Space Force’s website is https://www.spaceforce.mil/
  • The U.S Coast Guard’s website is https://www.uscg.mil/

Do All of the Military’s Subsidiaries and Affiliated Organizations Use “.mil”?

  • Its athletic programs sites (offered in service academies) use “.com”

The Department of Defense itself uses “.gov” – https://www.defense.gov/

Where Else Can You See “.mil”?

.mil is also used in military email addresses. Each member of the military has an email address with .mil in it. The format is standard, for instance:

Conclusion
