“What Does “Namespace” Mean in DNS?
In the Domain Name System (DNS), a namespace is simply the way all domain names are organized. Think of it as a giant map of names on the internet.
The DNS namespace is hierarchical, like a family tree:
- At the very top is the root (
.). - Below that are Top-Level Domains (TLDs) such as
.com,.org,.net, or country codes like.ca. - Under each TLD, you find second-level domains like
example.com. - You can then create subdomains such as
blog.example.comorshop.example.com.
This structure ensures that every domain name is unique and easy to locate. For example, google.com and google.org point to completely different places, even though both start with “google.”
👉 In short: The DNS namespace is the organized “address space” of the internet, making sure every website has its own unique spot in the global naming system.
