(1) I would wrap it all in a function

def main():
    # your code here

if __name__ == "__main__":

(2) PEP8 (python style guidelines) suggests one import per line

(3) I'd use four spaces as tab width

I'd change this:

>             if section == arg:
>                 count = count + 1
>                 break

to something more like:

    for section in hostname.split("."):
        if section in sys.argv[1:]:
            count += 1

(although as you suggested I'd only calculate sys.argv[1:] once)

... or you could replace whole section between the for loop and
hosts.append with:

    if sorted(hostname.split(".")) == sorted(sys.argv[1:]):

, at a slight loss of clarity - but I think I'd stick with the more
verbose version personally.
