The DNS (Domain Name System) is one of the pillars of the internet, allowing the translation of friendly domain names, such as www.exemplo.com, into IP addresses that computers use to identify each other on the network. Basically, DNS works like the Internet phone book. When you type a domain name into your browser, DNS is responsible for locating the server corresponding to the IP address associated with that name.
How DNS works
To understand this better, imagine that you want to access the website www.exemplo.com. Here’s the simplified process:
- Domain Name Entry: You type www.exemplo.com into your browser.
- Recursive DNS query: The browser sends a query to a recursive DNS server, usually operated by your Internet Service Provider (ISP).
- Querying Name Servers: The recursive server queries the DNS root servers, which indicate the authoritative name servers responsible for the specific domain.
- Answer with the IP address: The authoritative server returns the IP address associated with the domain, such as 192.0.2.1.
- Accessing the Web Server: With the IP address in hand, your browser can connect to the web server and load the site.
