How to lookup a website's IP address
Jump to
Every website has at least one IP address connected to its domain name. For example, the website Facebook has, among others, the IP address 157.240.214.35 connected to the domain name www.facebook.com.
When you enter a URL in your browser, it will first determine the domain name of that URL. It then looks up the IP address and connects to the server with this IP. Once connected, it fetches the website's source code to display the page.
These IP addresses are configured in the Domain Name System (DNS) as A and AAAA records. But how can you look up those IP addresses? That depends on the operating system you are using. Windows, Linux and Mac all have a different way of finding the IPv4 and IPv6 addresses. The sections below list the instructions for each operating system.
