Yes that's right, but that's why I was asking about the minimum footprint - let's say when statically linked. I just try to get some kind of "offical" numbers, since many people talk about it's small footprint.

Alright, according to my question, is the answer in this Thread (http://stackoverflow.com/questions/19349923/tcp-ip-stack-in-busybox) then wrong? There they say there is no TCP/IP stack in BusyBox.

Maybe I should have asked differently: will BusyBox be developped and supported in future or e.g.: will there be a successor program and therefore BusyBox would be left on a final state ?

Yes it did, many thanks
