DNS and OpenDNS FamilyShield

With ModemLockDown, you can set Domain Name Server or DNS settings on your machine that can't be changed by end users. Using an alternate DNS to your default one can offer benefits such as additional security, content filtering, phishing protection and parental controls.

ModemLockDown includes single click support for the OpenDNS FamilyShield service or you can enter specific DNS settings. OpenDNS FamilyShield is a free service that instantly blocks access to adult websites*.


Following your initial installation, you will be asked if you want to use the OpenDNS FamilyShield service.

If your trial period has expired and you have not purchased ModemLockDown, your chosen DNS settings will remain but may be changed by your users.


* The FamilyShield Service works by filtering Website names on a predefined list that is constantly updated. For caveats, terms and conditions, please visit OpenDNS.com
