So, you have probably already changed your dns entry but you probably still have some Windows, Mac, or Linux boxes that are still resolving to an old dns entry. It’s no problem at all to update your boxes dns cache. The only thing that you need to do is to FLUSH your DNS CACHE. Just follow the steps below for your OS:

1.) Flush your dns cache for Windows:
a.) Simply go to “Start” -> “Run” -> “cmd” or “command” and type “ipconfig /flushdns“.
2.) Flush your dns cache for Mac:
a.) Click on your desktop with the mouse and you will open up the “Finder” menu. Then go to “Go” -> “Utilities” -> “Terminal” and type the following:
I.) For Snow Leopard and Leopard: “sudo dscacheutil -flushcache
II.) For Tiger: “lookupd -flushcache
3.) Flush your dns cache for Linux:
a.) Open up a command terminal or console and type “/etc/rc.d/init.d/nscd restart” as the root user or using sudo(if you have sudo setup for your user).
