DNS, or Domain Name System, is a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network. It associates various information with domain names assigned to each of the connected devices using the TCP/IP protocol. DNS translates domain names into IP addresses, which are the numerical identifiers assigned to each device connected to a network that uses the Internet Protocol for communication.

Checking DNS on Ubuntu, a popular Linux distribution, is crucial for troubleshooting network connectivity issues, ensuring that devices can resolve domain names to IP addresses correctly. There are several methods to check DNS on Ubuntu, including using the command line or graphical user interface (GUI) tools.
