You can clear out your PC's DNS cache by flushing it but this is not always a solution as upstream proxies and ISP's on the network may also have an old cached DNS lookup that is being used.

Please see this link to learn how you can flush your DNS on a MAC: http://osxdaily.com/2008/03/21/how-to-flush-your-dns-cache-in-mac-os-x/
