### hexToMask(hex) | source code
converts a netmask represented in hex to octets represented in decimal. e.g. "0xffffff00" -> "255.255.255.0"

### asyncIpLookup(name) | source code
Look up an IP based on the name passed in. We use gethostbyname to make sure that we use /etc/hosts as mentioned above. This hasn't been tested.

### parse_iprange(iprange) | source code
  - Turn a string specifying an IP range into a list of IPs. Parameters: `iprange` (str
        >>> parse_iprange('10.0.0.1-5')
        ['10.0.0.1', '10.0.0.2', '10.0.0.3', '10.0.0.4', '10.0.0.5']
        >>> parse_iprange('10.0.0.1')
        ['10.0.0.1']
        >>> try: parse_iprange('10.0.0.1-2-3')
        ... except InvalidIPRangeError: print "Invalid"
        Invalid
) - The range string, in the format '10.0.0.a-b'
