In order to refresh the DNS cache in Mac OSX, execute the dscacheutil command with –flashcache as the parameter.

dscacheutil -flushcache
dscacheutil -statistics

Open terminal and execute the command

This command will reload the cache and now you should be able to resolve any domain names that were previously not mapping to an IP or were pointing to an old IP.[pb_builder]
