In my recent posting,, I suggested using OpenDNS as a defense against the current DNS flaw. OpenDNS provides excellent step by step instructions for modifying the network settings on your computer to use their DNS services.
The only omission in their instructions is the need to make this change for every type of network connection. On a laptop computer, for example, you would need to modify both the network connection for wired Ethernet and also the Wi-Fi network connection. If you use dial-up, that too, needs to be modified.
Chose your Operating System:
The Continue button at the bottom of the instructions invites you to open an account with OpenDNS. This offers useful and free services but opening an account is not required.
