DNS flush

All of the websites you visit get their domain resolved to get their IP address so you can actually connect to it, right?That information is stored locally in a cache. Then there is the occasions when you know the IP address of the server has changed but you still got the caches version. What to do? Flush the cache! The way to do this differs from OS to OS. Below I have mentioned how to do this on the most popular systems. If you know about how to do this on other systems feel free to leave a comment.:-)

Leopard: Open Terminal.app (search for it with Spotlight), then write on the command: dscacheutil -flushcache Voilá!
Tiger: Open Terminal.app (search for it with Spotlight), then write: lookupd -flushcache Voilá!
Windows: Click Start->Run. Type cmd into the text field, then write: ipconfig /flushdns Voilá!
Linux: Open your terminal or shell of choice and, run /etc/rc.d/init.d/nscd restart Voilá!
