"#include <netinet/in.h>

The header file in.h contains constants and structures needed for internet domain addresses."

    Sorry, My English is not very well. I don't understand why "netinet" means "Internet". – user18947 May 30 '11 at 15:45

    Presumably it was named that way to signify that the directory contains networking headers ("net"), more specifically for the internet protocols ("inet"). – James Henstridge May 30 '11 at 23:26
