Instructions for Windows and Mac: http://www.tech-faq.com/how-to-flush-dns.html (its Linux instructions aren't correct for all distributions)

Also, if you're using trisphee.com, try www.trisphee.com; if you're using www.trisphee.com, try trisphee.com -- sometimes the DNS might update one before the other. For me, for instance, trisphee.com works but www.trisphee.com doesn't.

In the worst case, you may need to wait a few hours to a couple days for your ISP to update its DNS cache.
