That makes sense. Since you, or someone else using your ISP's nameserver, had done a lookup on topazdesigns.com prior to the IP address change, the old info was cached. But nobody had done a lookup on www.topazdesigns.com, so when you tried that, it wasn't in the nameserver's cache, so it was forced to do a query, and it came up with the new IP address. So, you end up with two addresses for the same site, one old, one new. I never thought of it before, but it does seem to be a useful technique to bookmark both versions of the address - use the main one normally, and try the alias if the main one fails. And now, back to your regularly scheduled DX program...
