	in config.h:

	typedef int32_t nsaddr_t;

	struct ns_addr_t {
	   int32_t addr_;
	   int32_t port_;
	};

	in ip.h:

	struct hdr_ip {
	...
	 ns_addr_t src_;
	 ns_addr_t dst_;
	...
	 nsaddr_t saddr() {return src_.addr_;};
	 nsaddr_t daddr() { return dst_.addr_;};

	Quite confusing that the only difference is a "_"

	Well, as you see, simply an int.

	the own ip address if you have the node id:
	#define MY_IP  Address::instance().get_nodeaddr(((MobileNode*)(netif_->node()))->address())

	I use this inside the MAC layer.
