Here at Fast Hit we often get calls with people saying, “Oh, our web site doesn’t work, we get could not connect errorâ€! 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.
More info is here: http://www.ausbusiness.net/review/clear-dns-cache-flushdns/
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!
