why change your dns settings
One of the easiest ways to configure web filtering is to change your DNS servers to OpenDNS. Change the DNS server on your router and youâll be able to configure parental control settings on the OpenDNS website, allowing you to block certain categories of websites and view the websites accessed from your home network.f the website is blocked in this way, changing your DNS server to a third-party DNS service that doesnât block the website will allow you to access it. A real-world example of this occurred when The Pirate Bay was blocked in the UK. People could change their DNS servers to access it again.
