The DNS Cache stores information on the IP address that any given domain or subdomain points to. This is separate from your browser's cache of visited pages. Emptying your DNS Cache will force your computer to request updated DNS information. However, as your Internet Service Provider may also have cached DNS information, it may take up to approximately 48 hours to receive fully updated DNS information after a change has been made.
To empty your DNS Cache:
1. Open the Command Prompt or Terminal. If you are unsure how to do this, it is explained in the linked tutorial.
Windows 2000/XP/Vista:
2. Enter ipconfig /flushdns
Macintosh OS X:
2. Enter lookupd -flushcache
Macintosh OS X 10.5 (Leopard):
2. Enter dscacheutil -flushcache
Linux:
2. Restart the nscd daemon by entering /etc/init.d/nscd restart
