The packets are parsed into a chain. The first item is an "ethernet" object because the packet is an Ethernet frame. Further down the chain, there may (or may not) be an IP header. You need to find it (if it's there) and get its .srcip attribute. The last example of the introductory part of the "Working with packets" section of the POX manual wiki demonstrates exactly this. Good luck. -- Murphy
