I was going to say that there was a small typo when trying out 127.0.0.1:

"127.0.0.1 is a bogon or private IP address that should not appear on the Internet."

But then I learned that "bogon' is actually a word:

http://en.wikipedia.org/wiki/Bogon_filtering

And re-reading the sentence, I'm not sure what "bogon" would be a typo for anyway..."Vogon"? Anyway, good handling of an edge/nonsense case!
