R6260 Router changes its WAN/LAN addresses after changing DNS servers
This has happened twice now. I'll describe the latest. The router was a 10.0.0.1, DHCP set for 10.0.0.2 to 10.0.0.50. DNS servers were set for 10.0.0.11 and 1.0.0.1. Changed The 10.0.0.11 to 1.1...

Checking my phone, the local network is now 172.16.0.nnn. Changed my desktop to that and now it connects, had the change the printer port the same way.
What is the make and model of the modem/gateway/ONT that connects the router to the Internet?
Sounds like it could be a modem/router.
Out of the box, the R6260 likes to use the IP address 192.168.x.x. When you set it up, of it sees another router it will got for something like 10.x.x.x to avoid conflicts.
Two routers on your network can cause headaches. For example, you can end up with local address problems. Among other things, the other router can misdirect addresses that the Netgear router usually handles, such as routerlogin.net or the usual IP address for a router, 192.168.1.1.
This explains some of the other drawbacks.

It may be possible to put the modem/router into modem only (bridge) mode and then to use the second device as the router. Sometimes it is easier to put the second router into AP mode. But that has its own drawbacks:

Hmmm, I just found Get "Dynamically from ISP" selected. I've switched it to "Use Static IP Address", which is what I always thought I had selected. Hopefully that fixes my issue.
I'm running just one router, with a 4-port switch connected to it.
Thanks for responding. It got me looking where I didn't double check.

Be careful not to get confused by WAN and LAN addresses. DNS server addresses are nothing to do with those.
What address is set to get "Dynamically from ISP". WAN or DNS? They have nothing to do with the 10.x.x.x and 192.168.x.x. addresses which are local to you.
The WAN address is in the hands of your ISP. Most ISPs hand out an WAN address that can change as it likes. They may charge for allocating a fixed WAN IP.
This has nothing to do with the LAN IP address. That is something that is private to you and isn't related to the DNS server. That's something related to your connections to addresses on the Internet.
Many ISPs have their own preferred DNS server. But there are public DNS servers out there that can be useful. Most users can safely ignore this.
Your setup is so simple that it would be a good idea to reset the router, set it up again and leave things alone until you hit a problem. Then work out how to fix it.
As it is, the changes you say you made make no sense and are likely to cause problems.
