IP Filter (Score 1)

Beautiful code is not only defined by the quality and efficiency of it's statements. It's also defined by the quality of the design of the whole, and in the maintainability of the app/code. That's one of the reason why I really like digging into Darren Reed's code of IP Filter, I think it is ressourceful to see good code like this, that implement standards correctly and cleanly, and that use the features of the language without abusing them.
