DNS, short for 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 a database system. The primary role of the DNS is to translate human-readable domain names, like example.com, into IP addresses. It enables efficient navigation and communication by resolving domain names into numerical IP addresses that computers use to locate and connect to each other.
Checking your DNS involves verifying that your device is using the correct DNS settings to resolve domain names into IP addresses accurately and efficiently. Incorrect DNS settings can lead to connectivity issues, slow browsing speeds, or even security concerns. Regularly checking and updating your DNS settings if necessary can help ensure optimal internet performance and a secure online experience.
