Here's the simplest way to hack DNS to speed up your Web browsing: Use free, superfast DNS servers run by the OpenDNS service instead of your ISP's DNS servers. OpenDNS has a monstrously big DNS cache, with DNS servers around the world, so you'll be able to retrieve IP addresses from it more quickly than from your ISP's DNS servers.

Thought I might try this (setting for Open DNS) but before doing so thought I ask here for opinions as to wisdom of this.
Currently on Rogers Cable (low level: 135/) IP & DNS both Automatic.
What possible problems should I watch out for (if any)?
If I try and have problem, will System Restore find/reset to automatic (which is unknown as nothing showing currently) upon using?
Thanks in Advance for opinions!! Sandy
