I use OpenBSD's pf and, with its label feature, it is not difficult to
extract statistics with a shell script.  Right now I am looking at traffic
type, not IP addresses.  It all depends on how you create your rules. 
Below is a sample pf rule and the output my script provides me.

pass out on $EXT \
        inet proto udp \
        from $EXT to any \
        port 123 \        
        keep state \
        label "outbound - $proto:$dstport ->"
