I was trying to visualize the traffic generated by the web client in Examples > Ethernet

The analyzer is a windows machine running a bridge and wireshark capturing traffic to/from arduino, please refer to attached figure
What i do not understand is all the packets (also to port 80) which always precede the http request (highlighted in yellow) coming from arduino.
These packets appear when the request is to google or to a wamp server on my LAN
when i replace arduino by a window machine making the same request with wget, the first packet is the always http request
I’d greatly appreciate if anyone could shade some light on this mystery
