Um, no. That controls the _destination_ IP address, not the
source. If you want to control the source IP addresss you can
bind it to a local interface's IP address before doing the
connect() call.
sock.bind(('10.0.0.99',-1)) # -1: don't care about source port number
sock.connect((host,port))
That will make sure that 10.0.0.99 is used as the source IP
address. Of course you have to have an interface with that
address.
