Test Your DNS Servers - RouterSecurity.org
www.routersecurity.org › testdnsWe need tests like these because there are four places that DNS servers could have come from: (1) the router a computing device is connected to, (2) the computing device itself, (3) VPN client software running on the computing device or (4) a web browser configured to use encrypted DNS (DoH or DoT). Then again, your computer probably supports a system-wide DNS setting and also DNS settings specific to each wireless network (SSID) and maybe DNS settings specific to Ethernet connections. Whew.
