You can add capability of raw socket to the executable, hence run as non-root.
Since what you're asking means potentially send illegal (unrouteable) IP packets, I guess that indeed the kernel will require special privileges to enable you to do that. As I said, you can mitigate that with capabilities, or use the old method of start as root, bind socket and drop privileges, or use a small server creating such sockets running as root.
