@user_yw8z5o​ I'm not seeing that Xfinity DNS (75.75.75.75 anyway) is blocking access to your DNS.  At least I can query their servers using Xfinity's.  Maybe there is some other cloud edge issue. Something to try since you got a Netgear

I use an Arris cable modem that I own. Can I not choose a DNS server of my own on it? Also, if I set my choice of the DNS server on my router that is bridged to the cable modem, will the DNS lookups still go through Comcast servers?

Unable to ping

I do not have any difficulty to load websites, search with Google, and use the internet to stream video. However, I am unable to ping any DNS servers, including the primary and secondary DNS servers shown in my router. Those are 75.75.75.75 and 75.75.75.76. Neither can I ping Google DNS at 8.8.8.8.

Hello and hope you are doing well! I am glad to hear you were able to get in by changing DNS servers, avi_83. That is certainly odd if you were unable to get in with the normal XFINITY DNS as I am able to. To be sure, 75.75.75.75 and 75.75.76.76 are

I agree with @EG , it's probably not an actual DNS issue. You can change the DNS servers pretty easily to verify:   Google DNS Preferred: 8.8.8.8Alternate: 8.8.4.4   OpenDNS Preferred: 208.67.222.222Alternate: 208.67.220.220

No. That is regular Comcast DNS server queries / traffic on DNS port 53. Your firewall is being a hypochondriac in its announcements. It is doing its job.
