Windows 10/11 not respecting DNS server settings

[jnelsoninjax]

I've got my machines set to 9.9.9.9 along with static i.p. addresses, but for some reason they are not using it, they appear to be using Google DNS. I'm unable to access the modem/gateway due to the ISP changing the password. I also tried changed to nextdns.io and it still is not using it. Any ideas as to why or how to fix it?

set the dns, then open an admin command prompt and try

ipconfig /release
ipconfig /renew
ipconfig /flushdns

edit i realize this is probably on home and i think registerdns is mainlly when on AD

OK, I'll try those, but shouldn't windows automatically apply the new settings upon reboot?

New issue showed up now, whenever I switch to manual DNS and input the address, as soon as I close the window the internet drops from the PC, if I switch back to automatic, it comes back up. Also, I can not input any changes from the network control panel, I have to do it from the adapter settings, if I try via the control panel I get an error that says Windows is unable to validate some of the settings. The settings I use are IP address 192.168.0.4, subnet mask length 24, preferred DNS 9.9.9.9 alternate 146.112.112.112, but this yields the error, but if I input it Into the adapter settings it accepts it.

Show screenshots of what you are entering into Windows settings, not the adapter configuration. I want to see what Windows will not accept.

This probably won`t help the issue but I notice you`re using Quad9 for DNS. The secondary DNS should be 149.x.x.x not 146.x.x.x

Maybe disable the DNS server service while making the changes. Could security software be stopping you from making changes.

I realize this pic is incorrect on the subnet, I corrected it to 24 after I realized I made an error and it still does not work.

Yes, and as soon I as I save the info, the adapter goes to not connected, confirmed via ping that there is no internet connection

Can you ping the DNS servers? try pinging by IP address when that happens.

 

Ping cnn:

151.101.67.5

OK, this time all I had to do was an ipconfig /renew, and it came right back up and is working, and is using quad 9 DNS

Some apps, such as Google chrome, have it's own built in DNS Resolver.

That may be, but I was getting the information from ipconfig, not from the browser.
