Args:
address: A string or integer, the IP address. Either IPv4 or

be considered to be IPv4 by default.
Returns:
An IPv4Address or IPv6Address object.

Args:

be considered to be IPv4 by default.
Returns:
An IPv4Network or IPv6Network object.
Raises:
ValueError: if the string passed isn't either a v4 or a v6

Args:
address: A string or integer, the IP address. Either IPv4 or

be considered to be IPv4 by default.
Returns:
An IPv4Interface or IPv6Interface object.
Raises:
ValueError: if the string passed isn't either a v4 or a v6
address.
Notes:
The IPv?Interface classes describe an Address on a particular
Network, so they're basically a combination of both the Address
and Network classes.

Args:

Returns:
An iterator of the summarized IPv(4|6) network objects.
Raise:

If the first and last objects are not the same version.
ValueError:
If the last object is not greater than the first.

collapse_addresses2 s4
rN c C s( t | tr| j S t | tr$| j S tS )a2 Return a key suitable for sorting between networks and addresses.
Address and Network objects are not sortable by default; they're
fundamentally different so the expression
IPv4Address('192.0.2.0') <= IPv4Network('192.0.2.0/24')
doesn't make any sense. There are some times however, where you may wish
to have ipaddress sort these for you anyway. If you need to do this, you
can use this function as the key= argument to sorted().
Args:
obj: either a Network or Address object.
Returns:
appropriate key.
