I am going to start keeping a list of free DNS servers. I am seeing some weird things happening online. There was big talk about some DNS virus out there at DNS Changer Working Group (DCWG) . It seemed to come and go without incident. But now there are some sites that I was able to view before and now I cannot. But I can view these sites on other networks other than my home network. So I wonder if the DNS servers I use are affected.
