Are Domain Names Case Sensitive?

The short answer is no, domain names are not case sensitive. Regardless of whether you type a domain name in uppercase, lowercase, or a mix of both, web browsers will interpret the address in the same way and direct users to the intended website.

This lack of case sensitivity in domain names serves an important practical purpose. It ensures that accessing websites remains straightforward and error-free for end-users, who may not always remember the exact capitalization of a domain. This approach helps to minimize potential confusion and makes the web more accessible.

However, it’s important to note that while domain names themselves are not case sensitive, the same principle does not always apply to subdomains and file paths. Subdomains generally follow the same case-insensitive rule as main domains, but file paths can be case sensitive, especially on servers running Unix-based operating systems.
