Changing the DNS on my machine didn't work...

I've learned from the forums (and from the Open DNS site) that you can't change the DNS settings on the Arris router. I tried to set my laptop to Open DNS by changing the settings on it, but apparently the router settings override my local setting. 

 

Hard to believe that this lockdown is for "security reasons."

Actually..... it is. It's to prevent a type of attack called a DNS hijack, wherein your router or device is compromised so all the DNS requests are sent to a spoof site. 

 

If you really want to change your DNS settings, you''ll need to get a personal router, plus you'd need set your Comcast gateway to Bridge Mode or use your own modem.

FWIW, due to a firmware update, the Comcast supplied gateway devices no longer function as DNS forwarders / relays, so now you cannot even change the DNS servers in the individual network clients...

It has nothing to do with security, and everything to do with data mining and selling your data.

 

Some browsers will start supporting DNS over HTTPS, which cannot be tracked.
