How to block ads on router level?

It can be set up literally on any platform — PC, Mac, Android, iOS, etc.
DNS requests are encrypted, which protects you from possible request interception and subsequent eavesdropping and/or alteration.

DNS over HTTPS (DoH)
DNS over HTTPS is a new protocol designed to encrypt and secure DNS traffic over HTTPS (or HTTP/2).
It prevents DNS hijacking and ISPs from sniffing your traffic. We built an anycast network for our DoH service to give you a good performance.

The Domain Name System (DNS) is the phonebook of the Internet. Humans access information online through domain names, like nytimes.com or espn.com. Web browsers interact through Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so browsers can load Internet resources.
Each device connected to the Internet has a unique IP address which other machines use to find the device. DNS servers eliminate the need for humans to memorize IP addresses such as 192.168.1.1 (in IPv4), or more complex newer alphanumeric IP addresses such as 2400:cb00:2048:1::c629:d7a2 (in IPv6).
