Refresh DNS

13th February 2010

Interpreted as: How do I flush the DNS cache?

When DNS changes have been made to a domain the old DNS record may be cached in the system. In order to clear this cache it is necessary to refresh the DNS, this process is known as flushing the DNS cache.

Once the DNS has been flushed, the system will perform a full DNS lookup on the domain the next time it is requested instead of looking in the systems local cache.

For more information, check out the Flush DNS page for up to date information on flushing the DNS on a variety of operating systems including Windows 2000, Windows XP, Windows Vista, Windows 7, Mac OS X and Linux.
