Here at Fast Hit we often get calls with people saying, “Oh, our web site doesn’t work, we get could not connect error”! This often happens with web sites that just were moved to a new IP and the computer has the old IP cached in the DNS.

So, how about trying to clear the DNS cache (of flash DNS cache)? It’s easy.

In Microsoft Windows, you can use the command ipconfig /flushdns to flush the DNS resolver cache.
You can also use the command ipconfig /displaydns to view the DNS resolver cache.
C:\>ipconfig /flushdns
C:\>ipconfig /displaydns

In Mac OSX, you can use the command lookupd -flushcache to flush the DNS resolver cache.
bash-2.05a$ lookupd -flushcache
If still doesn’t work, try rebooting your computer and your router!
