Flusing the DNS cache
Posted by jpluimers on 2010/09/10
DNS is the fundament for resolving names to IP-adreesses.
Without it, no internet browsing or other connections to the outside world.
Like a lot of communication optimizations, caching improves the speed of DNS too ([Wayback/Archive] All programming is an exercise in caching -Terje Mathisen).
Sometimes, bad or unwanted DNS entries end up in your cache.
Those prohibit some of the communication.
Luckily, How to Flush DNS explains this for 3 platforms: Windows, Mac OSX and Linux:
- Windows:
ipconfig /flushdns - Mac OSX:
10.5 and up: dscacheutil -flushcache
pre 10.5: lookupd -flushcache - Linux:
/etc/init.d/nscd restart
