The 4.2.2.1 - 4.2.2.6 are open DNS servers belonging to Level3, a CLEC acquired by Verizon I believe or some other telco some some people argue they're Verizon DNS numbers but they do come back as registered to Level3. They're free, fast, and reliable. I use them all the time. Try pinging each IP address and see which one might be faster for your location. I find 4.2.2.3 is faster for my home and 4.2.2.1 is the 2nd fastest. Speakeasy also has open DNS and so does Sprint.
198.59.109.7 is also an intentionally public DNS server.
Thanks for the help everyone, but I think I found my best DNS servers now.
