Q: How do I protect my family from Adult content, while on the internet?

A: To protect against home users adult themed content, we recommend a passive first line defense, it is however not a ‘silver bullet’ solution,
change the DNS servers in the router to Primary DNS Server and Secondary DNS Server

If requested, we can issue these adddress to the router at home, so as to save you from the tech stuff.
for a more comprehensive solution, we recommend, you point your web browser to
