How to convert CIDR to IP ranges using python3?

How to convert list like: 

94.192.0.0/14  
94.0.0.0/12  
93.96.0.0/16

To: 

94.192.0.0-94.195.255.255  
94.0.0.0-94.15.255.255  
93.96.0.0-93.96.255.255

Using python3?

Solution

  • Use the ipaddress builtin module:

    >>> import ipaddress

>>> net=ipaddress.ip_network('94.192.0.0/14')
IPv4Network('94.192.0.0/14')

>>> '%s-%s' % (net[0], net[-1])
'94.192.0.0-94.195.255.255'

     

    With for i in net you can also enumerate all ip addresses in the network net.
