Domain namespace

Updated: 06/22/2024 by Computer Hope

Alternatively called a namespace, a domain namespace is a name service provided by the Internet for Transmission Control Protocol networks/Internet Protocol (TCP/IP). DNS (Domain Name System) is broken up into domains, a logical organization of computers that exist in a larger network. Below is an example of the hierarchy of domain naming on the Internet.

In the example above, all websites are broken into regional sections based on the TLD (Top-Level Domain). With http://support.computerhope.com, it has a ".com" TLD, "computerhope" as its second level domain (local to the .com TLD), and "support" as its subdomain, which is determined by its server.

Tip

Those who are setting up a network can also create private networks with their domain namespaces.
