How to get IP address using jpcap?

[yikaikai]

I got the code from
http://netresearch.ics.uci.edu/kfujii/jpcap/doc/index.html

but how can I get IP address from packet?

public void receivePacket(Packet packet) {
System.out.println(packet);

After skimming the javadocs, I'd say you need to do something like
this:

if (packet instanceOf IPPacket) {
IPPacket ipp = (IPPacket)packet;
InetAddress dest = ipp.dest_ip;
InetAddress src = ipp.src_ip;
}
