DNS - Cache

About

A DNS cache is a cache of the result of a DNS lookup (query)

Example: How to flush

Chrome

Web Browser - Chrome

  • Type in the address bar
chrome://net-internals/#dns 
  • and press the “Clear host cache” button.

Linux

To clear your local DNS cache, you have to type

ipconfig /flushdns

This is important when you try to troubleshoot a network problem because if a name is already cached it won't try and resolve the name again.

Network - ipconfig
