It seems that I am not too busy, so here is a code which may work with
a few tweaks here and there:
_________________________________________________________________________
import os
# base and range of the ip addresses
baseIP = "10.0.0."
r = 6
interestingPort = 22 # port that you want to scan
myIPs = []

for i in range(r):
        ip = baseIP+str(i)  # It may need some customization for your case
        print "scanning: %s" %(ip)
        for output in os.popen("nmap %s -p %s" %(ip,
interestingPort)).readlines():
                if output.__contains__('%s/tcp open'
%interestingPort):  # i guess it would be tcp
                        myIPs.append(ip)
__________________________________________________________________________
print myIPs


hth,
amit.
