So I'm trying to configure my Mac for use with OpenDNS since I think Charter's DNS servers are slowing me down.

I unplug my router.
Go to System Prefs
Network
Advanced
DNS tab
and there's nothing there (there is when I am connected but it's grayed out)
so I add 208.67.222.222 & 208.67.220.220, apply, etc...
Plug in the router and Charter's DNS servers are back in there in addition to the OpenDNS ones at the bottom.

Why? Why is my Mac automatically setting the DNS?
 
It's not. Your modem/router is providing them to the computer, thus the grayed out numbers. You would have to change the settings on the modem/router to remove those.

To use opendns, it's best to put the opendns ip addresses in your router settings.
 
Go here and pick your router for instructions: https://www.opendns.com/start

You obviously have a router that receives Charter's DNS information, which in turn is sent to all network devices via the router. So, you'll need to change the DNS servers manually at the router.
