Understanding DNS: The Internet’s Address Book

DNS (Domain Name System) acts like the internet’s phonebook, translating website names into IP addresses. When DNS gets corrupted or misconfigured, your internet connection suffers. This guide will walk you through comprehensive DNS troubleshooting strategies that work across different systems.

For Windows users, resolving DNS problems is straightforward with these powerful commands:

1. Flush DNS Cache To clear dns quickly, open Command Prompt as administrator and type:

ipconfig /flushdns

This command purge dns entries, refreshing your system’s DNS resolution. 2. Renew DNS Settings

ipconfig /release
ipconfig /renew

These commands reset network configurations and can resolve persistent connection issues.
