Apple Talk: How do I flush the DNS resolver cache on my iMac?

Flushing the cache and thus clearing out bad domain name servers, and etc. is relatively easy.  I know because I just did it.  Here is how:

GO TO:

Finder on your task bar

Open Applications

Open Utilities folder

Open Terminal

in Mac OS X Leopard…..

Type the following: dscacheutil -flushcache at the command line to flush the DNS resolver cache and then click ENTER (return).

Once you run the command your DNS cache will flush.

If using Mac OS 10.4 and below

Type lookupd -flushcache at the command line and then press ENTER (Return) to flush the DNS resolver cache.

That’s all there is to it!

    On Windows, you do a click on the lower start button at bottom.

    Then in the little space where you can type…type in “cmd”

    then when the dos looking window pops up type..

    “ipconfig /flushdns” and hit enter. Then to get back to windows, type “exit” or click on the x at the upper right corner.

      Young Mr. Krell you have passed your test and may now move on to the next form (class).

      All kidding aside thanks for the PC tip. Need lots of tech stuff. Know anyone interested in tech stuff? 🙂
