Is Domain Name Case Sensitive?

In this post you will get a simple answer to your “Is Domain Name Case Sensitive?” question, and useful information about case sensitiveness in URL parts.

Answer:

Domain names are case insensitive. It means, if you write domain name in uppercase, lowercase or mix, then in all cases – you will land on the same page.

For example,

If you type in the browser “https://techpostplus.com“, “https://TECHPOSTPLUS.COM” or “https://TechPostPlus.com“, then in the result your browser will open the same page for all cases.

Domain name case insensitivity helps to create uniqueness between domain names.

Note:

In URL, string(directory, page or file) after the domain name is case sensitive.

e.g., “https://example.com/page-name.html” URL is different from “https://example.com/PAGE-NAME.HTML“.
