 How do I flush the DNS cache on my local computer?
Solution The following steps explain how to flush a computer's DNS cache. When a computer visits a website for the first time, it stores the website's DNS information in cache. The next time the computer visits a website, it looks in the cache to see if the website's information is present to use. This can cause problems if the website's DNS information has changed since the computer's last visit. Flushing the cache removes all the information stored in cache, forcing the computer to find the new DNS information for the website.


To flush DNS on Windows, please follow these steps:

1. On your local machine, open a command prompt from Start –> Run –> type cmd and enter.
2. Type ipconfig /flushdns.

You should see the following message:


-------------------------------
Windows 2000 IP configuration
Successfully flushed the DNS Resolver Cache.
-------------------------------

To flush DNS on Mac OS, please follow these steps:

1. On your local machine, open a terminal window.

2. From the prompt, type lookupd -flushcache.
