DNS Cache


Your computer stores a list of IP addresses connected to various domain names. This list is generated as your browser requests DNS (Domain Name System) records from your ISP’s preferred DNS host.

Typing the following command in the Command Prompt that will save the result in a text file (dnshistory.txt) on C drive.
ipconfig /displaydns > c:\dnshistory.txt
Open the file on the C drive using Notepad (or any Text Editor). This file will contain a list of domain names accessed by the computer. Flushing the DNS now and then is also a great way to get over certain sites that may appear to be more sluggish than usual.

You can flush the DNS cache by typing the following command in the Command Prompt.
ipconfig /flushdns
