Virgin Media’s “Web Safe” product uses DNS

Virgin Media’s Web Safe product applies its blocking rules using its DNS servers, the same way the OpenDNS’s Family Shield does. I thought perhaps it was doing something cleverer.

I discovered this while looking for a way to block YouTube during home-schooling hours (don’t ask). Web Safe has some advantages over OpenDNS as it supports a timer option where its rules are disabled for defined periods each day/week.
