Returns:

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.

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:

Returns:
appropriate key.

Args:
address: A string or integer representing the IP [& network].
'192.0.2.0/24'
'192.0.2.0/255.255.255.0'
'192.0.0.2/0.0.0.255'
are all functionally the same in IPv4. Similarly,
'192.0.2.1'
'192.0.2.1/255.255.255.255'
'192.0.2.1/32'
are also functionally equivalent. That is to say, failing to
provide a subnetmask will create an object with a mask of /32.
If the mask (portion after the / in the argument) is given in
dotted quad form, it is treated as a netmask if it starts with a
non-zero field (e.g. /255.0.0.0 == /8) and as a hostmask if it
starts with a zero field (e.g. 0.255.255.255 == /8), with the
single exception of an all-zero mask which is treated as a
netmask == /0. If no mask is given, a default of /32 is used.
Additionally, an integer can be passed, so
IPv4Network('192.0.2.1') == IPv4Network(3221225985)
or, more generally
IPv4Interface(int(IPv4Interface('192.0.2.1'))) ==
IPv4Interface('192.0.2.1')
Raises:
AddressValueError: If ipaddress isn't a valid IPv4 address.
NetmaskValueError: If the netmask isn't valid for
an IPv4 address.

supplied.

Attributes: [examples for IPv6('2001:db8::1000/124')]
.network_address: IPv6Address('2001:db8::1000')
.hostmask: IPv6Address('::f')
.broadcast_address: IPv6Address('2001:db8::100f')
.netmask: IPv6Address('ffff:ffff:ffff:ffff:ffff:ffff:ffff:fff0')
.prefixlen: 124

@ | _ | j| jd kr| j| _dS )a Instantiate a new IPv6 Network object.
Args:
address: A string or integer representing the IPv6 network or the
IP and prefix/netmask.
'2001:db8::/128'
'2001:db8:0000:0000:0000:0000:0000:0000/128'
'2001:db8::'
are all functionally the same in IPv6. That is to say,
failing to provide a subnetmask will create an object with
a mask of /128.
Additionally, an integer can be passed, so
IPv6Network('2001:db8::') ==
IPv6Network(42540766411282592856903984951653826560)
or, more generally
IPv6Network(int(IPv6Network('2001:db8::'))) ==
IPv6Network('2001:db8::')
strict: A boolean. If true, ensure that we have been passed
A true network address, eg, 2001:db8::1000/124 and not an
IP address on a network, eg, 2001:db8::1/124.
Raises:
AddressValueError: If address isn't a valid IPv6 address.
NetmaskValueError: If the netmask isn't valid for
an IPv6 address.
ValueError: If strict was True and a network address was not
supplied.

This is like __iter__ except it doesn't return the
Subnet-Router anycast address.

zIPv6Network.hostsc C s | j jo| jjS )a` Test if the address is reserved for site-local.
Note that the site-local address space has been deprecated by RFC 3879.
Use is_private to test if this address is in the space of unique local
addresses as defined by RFC 4193.
Returns:
A boolean, True if the address is reserved per RFC 3513 2.5.6.
