If you're an MSDN subscriber and are sick of waiting for slow file transfers for the ISO images on the site, you'll be pleased to know that there is a solution.

The reason the download might be slow is the fact that a DNS lookup from your Internet service provider might return an IP for a replica MSDN download machine on a slow network. To connect to MSDN file servers on the faster networks, you will need to change your hosts file to resolve the following domain global.ds.microsoft.com into an IP address of a MSDN download server on the faster network. Also, you need to add the site to your trust list in Internet Explorer.

One of the IP addresses I've tested to work faster is: 207.46.252.185
