Well DNS based blocking has its problems mainly devices bypassing your network defined DNS with some encrypted DNS(DoT,DoH) or using hardcoded custom DNS servers.
A. Device part of a business infrastructure:
Just don’t change anything; those policy are there for a reason!
B. Consumer device:
1/ If we’re talking about proprietary hardware/software forcing your network to use a specific DNS, then you need to provide more details because you should be able to change it.
2/ There is also the case for a malware:
A fresh start is preferable.
Disinfect the system while offline, then back up the needed files.
Reinstall the system on a new/old formatted drive.
With the exception of taking your privacy/security seriously this time.
Sounds like you shouldn’t use those devices. I go for custom software personally so I can control the device itself
You are able to force devices to use a specified DNS. even when they have hard coded DNS in them. Your router/firewall must be able to support redirection of network traffic though.
This probably won’t work if the hard coded DNS is DNS over HTTPS
Yes but I think only very few applications use a hard coded DNS server. And under all those applications who use a hard coded DNS server is probably a very low percentage that uses encrypted DNS.
Or just a hardcoded IP, lol
A hard coded IP would mean it’s unencrypted DNS which can be force-redirected to your router with NAT rules.
True, don’t know how I missed that.
You need to use an IP address (as opposed to FQDN) for DNS because when your computer starts up, it won’t be able to resolve the FQDN to do DNS lookups.
Cloudflare DNS over TLS famously is using the IP address of 1.1.1.1: https://developers.cloudflare.com/1.1.1.1/encryption/dns-over-tls/
My computer uses unencrypted DNS and sends the queries to my router. My router does the encryption for forwarded DNS queries sent to the internet. There’s no need to encrypt DNS traffic in a LAN unless you don’t trust this LAN. The WAN (internet) is where evil people try to snoop on you.
