I have everything the script working with the socket() for my block of IP's, but want to reduce the load. Thus changing the code to only use the syn, syn/ack, rst to reduce network load thus reducing the overall time.

What is your basis for determining that you need to reduce a 7 packet connect/disconnect sequence to 3 packets? Are you really sure you need to reduce load, or might you be indulging in a round of premature optimization?

Unless you need sub-second awareness of new hosts, I wouldn't bother with this. A simple "can I open a socket to a port at this IP address" test is more sufficient, and more maintainable to whoever picks up the code after you move on.
