Those two numbers are the only two numbers in Network Preferences.
Then you are using OpenDNS servers to resolve your Domain Names into IP addresses (the numbers for websites)
Doesn't matter if you have a account with them or not, they allow people to use their DNS for free and customized options like content filtering is a added charge requiring a account.
I don't understand why something I'm not using has decided what I can and cannot access on the internet.
Your DNS settings were changed, your choosing to use OpenDNS as you have their numbers typed into your Network Preferences.
OpenDNS is blocking sites with the Flashback malware, and other bad sites, perhaps it actually saved your bacon and you dont know it.
You can choose another DNS service and enter new numbers into your Network Preferences.
Use the free NameBench here and run it, it will test the fastest DNS servers and also you will see your own ISP's DNS servers and can choose what you want to to reset them to. However you might not be getting any online protection.

Only perhaps your own ISP's DNS is not blockling anything, I think Google and OpenDNS etc are all blocking malware/attack sites by default.
If your paranoid, just to let you know everyone is recording everything. There is no privacy on the Internet really, just a illusion of privacy.
