Args:

Returns:
An IPv4Interface or IPv6Interface object.
Raises:

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.

a Summarize a network range given the first and last IP addresses.
Example:

... #doctest: +NORMALIZE_WHITESPACE
[IPv4Network('192.0.2.0/25'), IPv4Network('192.0.2.128/31'),
IPv4Network('192.0.2.130/32')]
Args:
first: the first IPv4Address or IPv6Address in the range.
last: the last IPv4Address or IPv6Address in the range.
Returns:
An iterator of the summarized IPv(4|6) network objects.
Raise:
TypeError:
If the first and last objects are not IP addresses.
If the first and last objects are not the same version.
ValueError:
If the last object is not greater than the first.

S )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.

a Returns an IP address as a formatted string.
Supported presentation types are:
's': returns the IP address as a string (default)
'b': converts to binary and returns a zero-padded string
'X' or 'x': converts to upper- or lower-case hex and returns a zero-padded string
'n': the same as 'b' for IPv4 and 'x' for IPv6
For binary and hex presentation types, the alternate form specifier
'#' and the grouping option '_' are supported.
