    """Given string search and string args: Return list of hosts on network
    'args' being nmap arguments to be passed to nmap for optimized searching on networks

    'search' defaults to current network subnet
    'args' defaults to '-sS -p 22 -n -T5'
    To break down these NMAP arguments:
        -sS  : TCP SYN scan. A fast unobtrusive stealthy scan that shouldn't raise any flags while remaining quick
        -p 22: Only scan port 22. This should speed things up while remaining fairly reliable
        -n   : No DNS resolution. Since we don't need the host names, we can go ahead and skip that
        -T5  : Insane timing template. This is the most unreliable, but also the quickest. If you have issues with
               assets being found, I'd suggest to start change with this option.
