Vlad Sorry for the super slow response.
So for instance Google has forcesafesearch.google.com. Bing has strict.bing.com. Those addresses have SafeSearch always on.
If you then reroute the google.com IP to go to the forcesafeseach.google.com IP (or you have your DNS provider do it via some sort of parental controls they might have), now your children or whatever can't just go and turn SafeSearch off.
