How does the browser resolve DNS?

Have you ever wondered how your browser resolves a domain name when you hit Enter on a URL? Here’s how it works, at a high level.

  1. Your browser first looks in its own cache for the address. If it doesn’t find it, it checks the OS cache, and finally the ISP’s cache.

  2. If the name isn’t cached, the next step is the /etc/hosts file. If there’s an IP address there, the browser tries to load the page from that server.
