-.. sectionauthor:: Gregory P. Smith <greg@krypto.org>
-
-
-.. versionadded:: 3.1
-
-.. index::
-   single: IP address, IPv4, IPv6, netmask
-
-This module implements classes for working with IP host and network addresses,
-both IPv4 and IPv6.
-
-
-.. _ipaddr_examples:
-
-Examples
---------
-
-Netmask.
-
-   >>> ipaddr.IP('1.1.1.1/255.255.255.0')
-   IPv4('1.1.1.1/24')
-   >>> ipaddr.IP('1080::200C:417B/96')
-   IPv6('1080::200c:417b/96')
-
-Hostmask.
-
-   >>> ipaddr.IPv4('1.1.1.1/0.0.0.255')
-   IPv4('1.1.1.1/24')
-
-Prefix length.
-
-   >>> addr = ipaddr.IPv4('1.1.1.1/24')
-   >>> addr.prefixlen
-   24
-
-Individual addresses.
-
-   >>> ipaddr.IP('1.1.1.1')
-   IPv4('1.1.1.1/32')
-
-Many standard Python operations are also supported.
-
-Comparison.
-
-   >>> ipaddr.IPv4('1.1.1.1') == ipaddr.IPv4('1.1.1.2')
-   False
-   >>> ipaddr.IPv4('1.1.1.1') < ipaddr.IPv4('1.1.1.2')
-   True
-
-Inclusion.
-
-   >>> ipaddr.IPv4('1.1.1.1') in ipaddr.IPv4("1.0.0.0/8")
-   True
-
-Sorting.
-
-   >>> a = ipaddr.IPv4('1.1.1.10')
-   >>> b = ipaddr.IPv4('1.10.1.10')
-   >>> c = ipaddr.IPv4('1.1.10.10')
-   >>> d = ipaddr.IPv4('1.1.1.1')
-   >>> sorted([a, b, c, d])
-   [IPv4('1.1.1.1/32'), IPv4('1.1.1.10/32'), IPv4('1.1.10.10/32'), IPv4('1.10.1.10/32')]
-
-Conversion to string and integer forms.
-
-   >>> spam = ipaddr.IPv4('192.168.1.254'))
-   >>> str(spam)
-   '192.168.1.254/32'
-   >>> spam.ip_ext
-   '192.168.1.254'
-   >>> int(spam)
-   3232236030
-   >>> eggs = ipaddr.IPv6('ffff::1/120')
-   >>> int(eggs)
-   340277174624079928635746076935438991361
-
-Additionally, there are quite a few network-specific features available to
-ipaddr.
-
-   >>> ipaddr.IPv4('10.0.0.0/8').supernet()
-   IPv4('10.0.0.0/7')
-   >>> ipaddr.IPv4('10.0.0.0/8').subnet()
-   [IPv4('10.0.0.0/9'), IPv4('10.128.0.0/9')]
-   # This returns networks with a prefix length of /10
-   >>> ipaddr.IPv4('10.0.0.0/8').subnet(prefixlen_diff=2)
-   [IPv4('10.0.0.0/10'), IPv4('10.64.0.0/10'), IPv4('10.128.0.0/10'), IPv4('10.192.0.0/10')]
-   # Remove an address from a superblock.
-   >>> ipaddr.IP('10.0.0.0/24').address_exclude(ipaddr.IP('10.0.0.0/28'))
-   [IPv4('10.0.0.16/28'), IPv4('10.0.0.32/27'), IPv4('10.0.0.64/26'), IPv4('10.0.0.128/25')]

-.. _ipaddr_funcs_and_classes:
-
-Functions And Classes
----------------------
-
-.. function:: IP(ipaddr)
-
-   Take an IP string or int and return an object of the correct type.  Returns
-   an :class:`IPv4` or :class:`IPv6` object.
-
-   The *ipaddr* parameter must be a string, bytes or integer representing the
-   IP address in ascii, network byte order or as a number respectively.  Either
-   IPv4 or IPv6 addresses may be supplied.  Integers less than 2**32 will be
-   considered to be IPv4.
-
-   Raises :exc:`ValueError` if the *ipaddr* passed is not either an IPv4 or an
-   IPv6 address.
-
-
-.. function:: collapse_address_list(addresses)
-
-   Collapse a sequence of :class:`IPv4` or :class:`IPv6` objects into the most
-   concise representation.  Returns a list of :class:`IPv4` or :class:`IPv6`
-   objects.
-
-   Example usage::
-
-      >>> collapse_address_list([IPv4('1.1.0.0/24'), IPv4('1.1.1.0/24')])
-      [IPv4('1.1.0.0/23')]
-
-
-.. class:: BaseIP()
-
-   A generic IP address object.  This base class defines the API and contains
-   common code.  Most authors should either use the :func:`IP` function or
-   create :class:`IPv4` or :class:`IPv6` objects directly rather than using this
-   base class.
-
-   IP address objects support the following python operators:
-   ``=``, ``!=``, ``<``, ``>``, ``<=``, ``>=``, and ``in``.
-
-   An IP address object may be used as a sequence index or as a hash key and can
-   be converted back to an integer representation using :func:`int`.  It may
-   also be used as a sequence that yields the string representation of every IP
-   address within the object's subnet.
-
-   The following properties are available on all IP address objects:
-
-   .. attribute:: broadcast
-
-      Integer representation of the broadcast address.  Read only.
-
-   .. attribute:: broadcast_ext
-
-      Dotted decimal or colon string version of the broadcast address.  Read
-      only.
-
-   .. attribute:: hostmask
-
-      Integer representation of the hostmask.  Read only.
-
-   .. attribute:: hostmask_ext
-
-      Dotted decimal or colon string version of the hostmask.  Read only.
-
-   .. attribute:: ip
-
-      Integer representation of the IP address.  Read only.
-
-   .. attribute:: ip_ext
-
-      Dotted decimal or colon string version of the IP address.  Read only.
-
-   .. attribute:: ip_ext_full
-
-      Canonical string version of the IP address.  Read only.
-
-   .. attribute:: is_loopback
-
-      True if the address is a loopback address as defined in IPv4 :rfc:`3330`
-      or IPv6 :rfc:`2373` section 2.5.3.
-
-   .. attribute:: is_link_local
-
-      True if the address is a link-local address as defined in IPv4 :rfc:`3927`
-      or IPv6 :rfc:`4291`.
-
-   .. attribute:: is_multicast
-
-      True if the address is reserved for multicast use.  See IPv4 :rfc:`3171`
-      or IPv6 :rfc:`2373` section 2.7 for details.
-
-   .. attribute:: is_private
-
-      True if the address is reserved for private networks as defined in IPv4
-      :rfc:`1918` or IPv6 :rfc:`4193`.
-
-   .. attribute:: netmask
-
-      Integer representation of the netmask.  Read only.
-
-   .. attribute:: netmask_ext
-
-      Dotted decimal or colon string version of the netmask.  Read only.
-
-   .. attribute:: network
-
-      Integer representation of the network.  Read only.
-
-   .. attribute:: network_ext
-
-      Dotted decimal or colon string version of the network.  Read only.
-
-   .. attribute:: numhosts
-
-      Number of hosts in the current subnet.  Read only.
-
-   .. attribute:: packed
-
-      The packed network byte order representation of this network address.
-      Read only.
-
-   .. attribute:: prefixlen
-
-      A property to get and set the prefix length.  Readable and writeable.
-
-   .. attribute:: version
-
-      Integer IP version number.  Read only.
-
-
-   The following methods are available on all IP address objects:
-
-   .. method:: address_exclude(other)
-
-      Remove an address from within a larger block.  Returns a sorted list of IP
-      address objects representing networks.
-
-      Examples::
-
-         >>> addr1 = IP('10.1.1.0/24')
-         >>> addr2 = IP('10.1.1.0/26')
-         >>> addr1.address_exclude(addr2)
-         [IP('10.1.1.64/26'), IP('10.1.1.128/25')]
-
-         >>> addr1 = IP('::1/32')
-         >>> addr2 = IP('::1/128')
-         >>> addr1.address_exclude(addr2)
-         [IP('::0/128'), IP('::2/127'), IP('::4/126'), IP('::8/125'), IP('0:0:8000::/33')]
-
-      Raises :exc:`ValueError` if *other* is not completely contained by *self*.
-
-
-   .. method:: compare_networks(other)
-
-      Compare this IP object's network to another IP network.
-      Returns -1, 0 or 1.
-
-      This compares the integer representation of the network addresses.  The
-      host bits are not considered by this method.  If you want to compare host
-      bits, you can use ``host_a.ip < host_b.ip``.
-
-      If the IP versions of self and other are the same, returns:
-
-      -1 if self < other
-        eg: IPv4('1.1.1.0/24') < IPv4('1.1.2.0/24')
-
-        IPv6('1080::200C:417A') < IPv6('1080::200B:417B')
-
-      0 if self == other
-        eg: IPv4('1.1.1.1/24') == IPv4('1.1.1.2/24')
-
-        IPv6('1080::200C:417A/96') == IPv6('1080::200C:417B/96')
-
-      1 if self > other
-        eg: IPv4('1.1.1.0/24') > IPv4('1.1.0.0/24')
-
-        IPv6('1080::1:200C:417A/112') > IPv6('1080::0:200C:417A/112')
-
-      If the IP versions of self and other are different, returns:
-
-      -1 if self.version < other.version
-        eg: IPv4('10.0.0.1/24') < IPv6('::1/128')
-
-      1 if self.version > other.version
-        eg: IPv6('::1/128') > IPv4('255.255.255.0/24')
-
-      .. note::
-
-         To sort networks with :func:`sorted`, :func:`min`, :func:`max` and
-         other tools with a *key* argument, use the :func:`operator.attrgetter`
-         function to extract the relevant fields::
-
-            >>> from operator import attrgetter
-            >>> s = [IPv6('::1/128'), IPv4('255.255.255.0/24')]
-            >>> sorted(s, key=attrgetter('version', 'network', 'netmask'))
-            [IPv4('255.255.255.0/24'), IPv6('::1/128')]
-
-   .. method:: subnet(prefixlen_diff=1)
-
-      Returns a list of subnets which when joined make up the current subnet.
-
-      The optional *prefixlen_diff* argument specifies how many bits the prefix
-      length should be increased by.  Given a /24 network and
-      ``prefixlen_diff=3``, for example, 8 subnets of size /27 will be returned.
-
-      If called on a host IP address rather than a network, a list containing
-      the host itself will be returned.
-
-      Raises :exc:`PrefixlenDiffInvalidError` if the *prefixlen_diff* is out of
-      range.
-
-
-   .. method:: supernet(prefixlen_diff=1)
-
-      Returns a single IP object representing the supernet containing the
-      current network.
-
-      The optional *prefixlen_diff* argument specifies how many bits the prefix
-      length should be decreased by.  Given a /24 network and
-      ``prefixlen_diff=3``, for example, a supernet with a 21 bit netmask is
-      returned.
-
-      Raises :exc:`PrefixlenDiffInvalidError` if the prefixlen_diff is out of
-      range.
-
-
-.. class:: IPv4()
-
-   This class represents and manipulates 32-bit IPv4 addresses.
-
-   Attributes::
-
-      # These examples for IPv4('1.2.3.4/27')
