using opedns for a while now and it works and is free. And guess what my router is supported. On this i can't get even if i wanted too cause my router is not supported? What i don't understand is don't you just change your dns settings on your router for this to work? I think they should rater put up a list of routers that is not supported.
All the privacy people jumping up and down, you _DO KNOW_ that any other DNS server you are using can log? and a profile can be built on you from previous IP addresses etc etc whether your ISP consolidates this or other. If having your DNS queries logged is worrying you I suggest you turn the wall-plug off on all internet -connected devices
Back on topic - the service is good for people who cannot afford or do not know how to setup an appliance-based or custom-built proxy/firewall for URL and content protection.
Might they log and sell your browsing habits? Possibly. But if you did not know there's another 20 ways for them to be already doing that you're in for a surprise
TIP - sometimes on an iPad i've found it blocks legitimate sites at random (although rare). I think its possibly a caching issue on the device but a simple off-and-on of the Wifi tends to fix it. Could also occur when you whitelist a site previously blocked even though OpenDNS is reflecting the changes.
