## Definition

the unique address used to find a website on the internet. It is the part of a web link that comes after 'www' and usually ends in something like '.com' or '.org'.

For teachers: a unique string of characters that identifies a specific website or internet resource. It serves as a human-readable alias for a numerical IP address within the Domain Name System (DNS).

## Examples

- You need to register a domain name before you build your website.
- The company spent thousands of dollars to buy the domain name that matched their brand exactly.
- Choosing a memorable domain name is a critical step in digital branding, as it influences both search engine rankings and the ease with which users can return to the site.

## Usage notes

- Often used as a compound noun; the two words are rarely hyphenated in modern usage.
