I switched hosts and ever since I can only reach my site by using the IP. If I type in the URL I get a page not found. My host says they can see the site okay and it must be a problem with my computer caching the dns. According to dnsstuff, the dns is okay and pointing to the right IP. Click here and let me know if the site comes up.

The site comes up just fine, I would contact your ISP and ask them if they could update thier DNS servers to included your new DNS nameservers. Info to have on hand would be the nameservers name and IP addresses.

I did that and still nothing. It must be a problem within my machine because everyone else has no problem with it.
