[DM-MUG] changing to Google DNS

If you open your Airport Utility app, click on your Airport, then on the Manual Setup button at the bottom of the window. Then click to the network tab at the top, and you'll see two slots for DNS servers, about halfway down the window. In my case, these were already populated (but grayed out because the numbers are provided by Mediacom). I replaced them with the Google Public DNS IP addresses.

Actually, this is probably the preferable way to roll this change across an entire network of computers and devices (e.g., iPhones, iPods Touches, etc.) because the change will be pushed to each of these devices the next time their DHCP leases are renewed.

Also, you should be able to add the Google addresses (or OpenDNS, etc.) to your Network Preferences even with the 10.0.1.1 address. The system will check the first server and, if it receives no response, move to the second. The interesting thing here is that 10.0.1.1 would be a private address. So, unless you're running your own DNS server, it's probably just skipping past it anyway to the options provided to the Airport via its DHCP lease from Mediacom.
