MacMost: Making the most of your Mac, iPod, Apple TV and iPhone.

    DNS is what finds Web sites when you are surfing. You type in a domain name, like MacMost.com and your ISP’s DNS server will figure out where that Web site is really located. But if that site has just moved, or if it was down recently, you may get an error instead. This error may persist even if the site if back up. This is because DNS information is cached on your Mac for quick access. So your Mac may have outdated DNS information.

    To clear your DNS cache, open the Terminal application. In Leopard, type:

    dscacheutil -flushcache

    In earlier versions of Mac OS, use this instead:

    lookupd -flushcache
