Router DNS Setup
Network-wide classic DNS, with honest limits
What this changes
A router can advertise resolver addresses to DHCP clients:
51.75.96.8251.89.95.33151.115.80.165
Look for LAN, DHCP or DNS server settings rather than the router’s upstream/WAN DNS alone. Save, then renew client DHCP leases.
What this does not change
Classic router DNS is not encrypted and does not prevent an ISP or on-path network from observing or intercepting port-53 traffic. Devices using hard-coded DNS, browser DoH, a VPN or mobile data can bypass the router’s DHCP setting.
For end-to-end encryption, use router-native DoT/DoH where the firmware supports a custom provider, or configure each device with DoT or DoH.
ISP routers
Menus and capabilities change with firmware. Some ISP routers do not allow custom LAN DNS. Do not disable DHCP or change unrelated WAN settings merely to force this configuration; use per-device encrypted DNS instead.
Verify
Renew the device’s network lease and inspect its assigned DNS servers. A DNS leak test is useful for spotting an ISP resolver, but hosting-provider labels are not definitive.
