host and network addresses. host and network addresses.
The :func:`ipaddr.IP` factory function creates an address object from
a string or integer representing the IP or the IP and prefix/netmask.
The objects provide a number of attributes for direct access to
components of the full address::
>>> addr = IP('2001:658:22A:CAFE:200::1/64')
>>> for attr in ['ip', 'ip_ext', 'ip_ext_full', 'network', 'network_ext',
... 'hostmask', 'hostmask_ext', 'broadcast', 'broadcast_ext',
... 'netmask', 'netmask_ext', 'prefixlen']:
... print(attr, '=', getattr(addr, attr))
...

Each address object supports a number of simple properties including:
``is_private``, ``is_multicast``, ``is_loopback``, and ``is_link_local``.
Additionally, the address objects provide a sort order for IP addresses,
support for address ranges (stored as lists of addresses), and subnet
computations.
