Website name

Website name

A website name (or domain) is what shows up in the browser tab and in search results, like webflow.com. It's what people type to find your site, and it sits right after the HTTP or HTTPS protocol in a URL, before the top-level domain extension like .com or .io.

A website has two parts — the domain name and a hosting server. The domain connects to its internet protocol (IP) address, a unique number set connecting a device to the internet, and redirects to the server that hosts it. When you enter a website's name into a browser, it sends a request to an international Domain Name System (DNS) server network. The DNS returns the website's IP address, making it accessible to users. No two website names are the same — one website can't use a domain occupied by another.

Domain names allow visitors to access websites by entering a memorable title instead of a complicated and difficult-to-remember IP address. In Webflow, your website name is the title used to describe your website throughout Webflow.

With Webflow, you can purchase a custom domain name and connect it to your created website to share it with the world. Learn more about connecting your domain to Webflow.
