What is an MS URL and What Does It Refer To?

Published in URL Definitions 3 mins read

An "MS URL" primarily refers to a shortened web address using the aka.ms domain, extensively utilized by Microsoft for its various online resources. However, it can also signify a website address that uses the .ms top-level domain, which, while officially assigned to Montserrat, finds secondary use by entities associated with the U.S. state of Mississippi.

Understanding the context helps differentiate these two primary meanings of an "MS URL."

Microsoft's Aka.ms URL Shortener

Microsoft extensively uses aka.ms as a dedicated URL shortener for its numerous web properties, documentation, and services. These short links are designed to provide users with easier-to-remember and type addresses for accessing Microsoft-related content.

  • Purpose:
    • To simplify long, complex URLs into concise, memorable links.
    • To brand Microsoft-related content consistently.
    • To facilitate easy sharing of resources, especially in presentations or printed materials.
  • Functionality: When a user clicks an aka.ms link, they are automatically redirected to the full, longer URL of the Microsoft website or resource.
  • Examples:
    • http://aka.ms/MFAsetup might redirect to a detailed guide on setting up multi-factor authentication for Microsoft services.
    • aka.ms/learn could point to the main page of Microsoft Learn, an online platform for educational content.

These URLs are a hallmark of Microsoft's digital presence, making their vast ecosystem of information more accessible.

The .ms Top-Level Domain (TLD)

The .ms domain is officially the country code top-level domain (ccTLD) for Montserrat, a British overseas territory in the Caribbean. However, the "MS" abbreviation has another significant association within the United States.

  • Official Assignment: The Internet Assigned Numbers Authority (IANA) designates .ms for Montserrat.
  • Mississippi Connection: The abbreviation "MS" is widely recognized as:
    • The official United States Postal Service (USPS) abbreviation for the state of Mississippi.
    • The ISO 3166-2:US code for Mississippi.
      Due to this strong association, websites based in or having to do with the U.S. state of Mississippi also utilize the .ms domain, alongside more common TLDs like .com, .org, or .gov. This usage helps to regionally identify a website's origin or focus for a specific audience.

Key Distinctions Between MS URL Types

To clarify the difference, consider the following table:

Aspect Aka.ms (Microsoft URL Shortener) .ms Top-Level Domain (TLD)
Primary Function Redirects to longer Microsoft-owned URLs Serves as the primary domain name for a website
Associated Entity Microsoft Corporation Montserrat; entities related to Mississippi, USA
Example http://aka.ms/MFAsetup (redirects to a Microsoft page) example.ms (a website for a Montserrat or Mississippi entity)
Nature A shortlink service A standard internet domain extension
Who Uses It Primarily Microsoft and its official communications Websites globally (for Montserrat) or specifically within the U.S. (for Mississippi-related content)

In summary, when encountering an "MS URL," it's crucial to consider the domain itself. If it's aka.ms, it points to a Microsoft resource. If it's a website ending in .ms, it typically signifies a connection to Montserrat or, in the U.S. context, Mississippi.
