Xfinity DNS and Roon

I have XFinity service and use a Netgear Orbi router. The DNS option has a selection for - Obtain DNS settings from ISP or - Use these DNS servers.  When I select the second option the boxes for setting the DNS server addresses are enabled.  I use:

1.1.1.1

1.0.0.1

These are the Cloudflare DNS servers.  That coupled with a VPN and Xfinity can't see what I'm doing.

Thanks.  So it doesn’t seem that it is not allowed by Xfinity them.  Just wondering if it is locked on this particular router.  It is fiber optic but I wouldn’t think that would matter.

You are using THEIR equipment, right? It is locked to them. Why I don't use their equipment. I really dislike comcast because of that.

1. DNS is not likely to be your problem but you SHOULD use OpenDNS.  Intermittent streaming is more of a network quality issue.

2. Your Roon device can have it’s DNS set locally, for instance every Mac/PC/Tablet lets you set the DNS service in the network settings, regardless of upstream components. This will override the router.

3. For security reasons I don’t use the cable provider’s router. In some cases they may give you a modem for free, and turn off the Wifi features. That’s fine. You buy your own Wifi router and wire it downstream from Xfinity or whoever, then you have 100% control AND can turn off remote access, which is a key security feature. They may break into my cable provider’s router but they won’t get any further.
