DNS
DNS (Domain Name System) is like the internet's phone book: it translates the website names you type in (such as www.example.com) into numeric addresses (IP addresses) that computers understand, allowing you to access websites.
How it works
When you enter a web address in your browser, your computer queries a DNS server for the corresponding IP address. This process is a key part of internet infrastructure — it lets us easily access websites and online services without having to remember long strings of numbers.
Examples
- 1.After you type 'google.com' into your browser, DNS resolves it to an IP address such as '142.250.74.46', which loads Google's search page.
- 2.When setting up a new website, you need to configure DNS records at your domain registrar to point your domain to the IP address of the server hosting your site.
