OpenDNS not working with Xfinity

I am trying to use OpenDNS (208.67.222.222) as my DNS server on the Netgear router as well as my laptop. While trying to dig (command used to query DNS records) www.google.com on my laptop terminal, I noticed that the dig command fails with the OpenDNS IP. 

I then tried to do a traceroute to the OpenDNS Ip 208.67.222.222, it can be seen that the packets never reach the OpenDNS server through Xfinity ISP. How can you fix this?
