Network interface objects

In the ipaddress module, we have a convenient class to represent an interface's IP configuration in detail: IPv4Interface. It takes an arbitrary address and behaves like a network address object:

>>> import ipaddress >>> eth0 = ipaddress.IPv4Interface('192.168.0.1/24') >>> eth0.ip IPv4Address('192.168.0.1') >>> eth0.with_prefixlen '192.168.0.1/24' >>> eth0.with_netmask '192.168.0.1/255.255.255.0' >>> eth0.network IPv4Network('192.168.0.0/24') >>> eth0.is_private True >>> eth0.is_reserved False >>> eth0.is_multicast False >>>

As you can see, a network interface, eth0, with the IPv4Address class, has been defined. It has some interesting properties, such as IP and network address. In the same way as the network objects, ...
