My mother's cable provider, Optimum Cable, routes DNS traffic to their own DNS servers.
To make matters worse, they engage in gratuitous blocking; for example, they won't resolve addresses of private networks (192.168.x.y, 10.x.y.z, etc...). For example, 192.168.1.1.nip.io won't resolve on my mom's network, but will almost everywhere else.
The solution, as another poster pointed out, was to use DNS-over-TLS.
