DNS (Domain Name System)
DNS is the 'phonebook of the internet', translating human-readable domain names into machine-readable IP addresses.
In plain English
The system that turns a name like google.com into the number (IP address) that computers use to find the server—so you don’t have to remember numbers.
The Domain Name System (DNS) is a hierarchical and decentralized naming system for computers or services connected to the Internet. It translates domain names (like example.com) into numeric IP addresses (like 192.0.2.1) required for locating and identifying computer services and devices with the underlying network protocols.
Understanding DNS is key to managing websites and email. Our tools help you inspect various DNS record types to ensure your services are running correctly.
