IP address

I was wondering if looking at the log files generated from dstumbler, If I
could determine the ip or range of ip that the node and/or ap is on.
I know that kismet will do that, but it doesn't like FBSD.
so can I figure out the ip address of the traffic I'm looking at, is it in
there someonewhere listed in hex or something that I don't know how to read.
or can I use some other utils to find that.
Thanks.
