tested -- does not block bad sites yet.
http://www.liutilities.com/how-to/find-your-dns-server-address/ the first 3 steps work to get a list of DNS servers (can't figure out their directions using control panel). See RUN, then CMD, the ipconfig /all gives lots of info.
In addition to the openDNS DNS servers, 208.67.222.222 and 208.67.220.220, this command also shows 209.18.47.61
youtube directions say just use the given IP address and give it a friendly name (like "home"). I already set the router, activated. I don't think i made an account yet.
This gpost is has even better instructions. It also says that I should use the detected IP address, and that most home networks are dynamic IP. For free version though. Said something about ISPs not liking the other?
Tekzilla video gives some alternatives to openDNS, as well as a tool to benchmark various DNS server speeds.
This youtube video shows how to force everyone using your router to use opendns (i.e. block port 53). It is specific for a certain router, however.
Various youtube videos show how to bypass openDNS.
openDNS may make problems for Content Delivery Networks like online movies. See this post to bypass openDNS for specific sites.
See Google safesearch to block google images
8/16/14 bought the $20/yr premium subscription.
Having trouble setting it up.
Setting the router DNS went fine (they have help pages). Use http://192.168.1.1 to access router. I also cleared the computer and browser cache as per these instructions.
They have sites that confirm things are working (see intro article): http://welcome.opendns.com, and (for a blocked site http://www.internetbadguys.com
https://www.opendns.com/dashboard/ to work on settings
Support pages on openDNS
apparently devices can use their own DNS settings, which are (can be?) "passed through" a router on port 53 (article here)-- but there may be ways to force traffic through openDNS
