I recommend looking for an on-device parental control solution instead. Routers can block IP addresses or ports. DNS servers can block specific domains. But everything after domain.tld/* is sent over a TLS connection, so the only way to block that at the network level would be by breaking encryption (for example, installing a custom root certificate on all client devices and using a man-in-the-middle proxy on a network appliance). All major operating systems (desktop and mobile) offer parental control options; most only work with the default browser (Edge on Windows) so either block the installation of 3rd party browsers (using the same system parental controls) or look for a 3rd party parental control solution that works with your browser. If they're using an app instead of a browser, things can get complicated.
