Does anything happen on the router without linked ip?

If I just replace my routers DNS servers with NextDNS's  servers, does it do anything at all? I know it won't use the same filters (such as blocking facebook), but i'm curious if there are any benefits to just using NextDNS dns servers on my router. For example, 1.1.1.1 does not sell user data to advertisers and has been measured to be a faster DNS resolver than my ISP.

As a side question. My router is the Netgear Nighthawk R7000P. Do you know if this router is capable of taking full advantage of NextDNS? From the research I've looked into, it seems not fully compatible. Since I would need something like openwrt or dd-wrt in order to take advantage of DNS-over-HTTPS.

If that's the case, I may buy a new/different router that is more compatible. Which one would you recommend that works well with NextDNS?

Last question. If a router is too expensive, would something like a RaspberryPi work with NextDNS, in order to setup DoH on my router to give my whole network more security/prviacy? Thanks for the help. Loving the product so far, and I may just pay the premium to get more out of it at $2/m.

    I also forgot to ask.

    1. If I use a Linked IP with my Router, would this be the same as setting it up through openwrt through DoH?

    2. If the answer to my 1st question is yes, it's the same. Then my next question is, what are the drawbacks to having a linked IP? Meaning, it seems like the easiest method to use, rather than having to go configure a bunch of things in the router.

    2.a) This is kind of a #2 part a, question (follow up to #1). If I use a Linked IP and put swap the DNS servers in my router with yours, does that make my entire network go over DoH ? Or is DoH only per device? For example. Would I still need to setup Firefox to use DoH? Or would a linked IP in my and dns router changes be good enough for the entire network? Was just curious if I still needed to change the servers per device or not.

    Sorry for so many questions. Thanks!

      Calvin Hobbes Yeah, I tried searching that already, and still haven't gotten clarification on many of my questions. The main one I would like to know is if Linking your IP allows for DoH. Or is that something you have to configure separately. For example.  If I link my IP, then replace the DNS server ips in my router, does all my network traffic now go through DoH? Or do I still have to go into firefox and configure DoH under my configuration code.

      j behr DoH is a protocol your router would need to implement or you need to install an extra software like our CLI to add the capability.

      Olivier Poitrey Gotcha, thank you Olivier. And I assume this would mean, if I don't have that kind of router, I would need to add DoH per Device, correct? Such as, setting up DoH in firefox on my desktop pc.

      j behr that or add a DoH proxy (like our CLI) on the side, running on something like a raspberry pi then configure your router’s DHCP with the DNS IP of the rpi so clients on your network would use it instead of your router for DNS resolution.

      Olivier Poitrey Thank you. I am actually trying to set this up right now on my Synology NAS device. It looks like you allow for it via Synology DSM through SSH. When I setup the DNS IP within my router, it gives two entries. Do I put the IP of my NAS for both entries, or just the first entry?

      j behr just one entry is necessary.

      Olivier Poitrey It installed correctly it seems. But when I check the status and/or try to activate it. It gives me this:

      ~$ nextdns activate
      Error: setup resolv.conf: write /etc/resolv.conf.nextdns-tmp: open /etc/resolv.conf.nextdns-tmp: permission denied
      ~$ nextdns status
      Error: /usr/local/etc/rc.d/nextdns.sh status: exit status 1:

      Olivier Poitrey i will continue this on github if you want. i figured out it was a root issue, but even after running the commands as root, the installation still does not work. i'll open an 'issue' on github

      j behr you need to use sudo before the command.

    I am still unclear, what happenes with my network using nextdns dns-servers, when the wan ip of my router is not linked.

    The update of the linked ip at nextdns servers can happen with max 10 min delay after provider DSL reconnection, as my dyndns account is updated by my NAS behind provider modem only every 10  min. 

    Do I still receive dns request replies from nextdns servers or will my web traffic be interrupted until ip is linked again 9 mins later?

    Or can I continue surfing the web but nextdns logging + filtering does not work until next ip linking?

      ChrisK the latter. We always answer to DNS queries.
