First of all, working from a picture is just a PITA, share capture files instead.
So only partial answers can be derived from this picture.
You're showing a DNS query packet, with 10.9.10.21 as the source (thus client) and 10.10.100.207 as the destination (server, or proxy). 74.125.226.55 is some host on an interconnected network, which you can reach via a router.
That is as far as this analysis goes. With a proper capture file we could possibly tell more.
