Found this linked from an internal forum post, and thought it worth sharing - mainly so I can find it again :-)
Flushing the DNS on Mac OS X Lion is quite simple. Just follow the below steps:
1) Change to "root" by using the following command:
su -
Enter the root password when prompted. If you don't know the "root" password for your system, you can set it by following this Apple KB article: http://support.apple.com/kb/ht1528
2) Type in the following command to flush the DNS:
dscacheutil -flushcache
The DNS has now been flushed.

Rather than setting a root password, just use sudo
sudo dscacheutil -flushcache
Then enter the password for your own account.
@Adrian, yes, absolutely true. I was quoting directly from the article, but I'd also use sudo rather than su.
I referenced this in an earlier blog post about flushing routes - http://portal2portal.blogspot.co.uk/2009/10/when-your-vpn-doesnt-want-to-play-ball.html.
Hope all is well with you and the family, Dave
