dscacheutil: Clearing DNS cache on OSX

Written by Benjamin Cane on 2011-10-25

This is something I ran into recently over the weekend. I made modifications to the DNS of a domain and I couldn't get my mac to recognize the change.

The culprit was DNS caching, after flushing my DNS cache all was well.

# dscacheutil -flushcache
