Description: IPy - class and tools for handling of IPv4 and IPv6 addresses and networks.
        
        Website: https://github.com/haypo/python-ipy/
        
        Presentation of the API
        =======================
        
        The IP class allows a comfortable parsing and handling for most
        notations in use for IPv4 and IPv6 addresses and networks. It was
        greatly inspired by RIPE's Perl module NET::IP's interface but
        doesn't share the implementation. It doesn't share non-CIDR netmasks,
        so funky stuff like a netmask of 0xffffff0f can't be done here.
        
            >>> from IPy import IP
            >>> ip = IP('127.0.0.0/30')
            >>> for x in ip:
            ...  print(x)
            ...
            127.0.0.0
            127.0.0.1
            127.0.0.2
            127.0.0.3
            >>> ip2 = IP('0x7f000000/30')
            >>> ip == ip2
            1
            >>> ip.reverseNames()
            ['0.0.0.127.in-addr.arpa.', '1.0.0.127.in-addr.arpa.', '2.0.0.127.in-addr.arpa.', '3.0.0.127.in-addr.arpa.']
            >>> ip.reverseName()
            '0-3.0.0.127.in-addr.arpa.'
            >>> ip.iptype()
            'PRIVATE'
        
        
        Supports most IP address formats
        ================================
        
        It can detect about a dozen different ways of expressing IP addresses
        and networks, parse them and distinguish between IPv4 and IPv6 addresses:
        
            >>> IP('10.0.0.0/8').version()
            4
            >>> IP('::1').version()
            6
        
        IPv4 addresses
        --------------
        
            >>> print(IP(0x7f000001))
            127.0.0.1
            >>> print(IP('0x7f000001'))
            127.0.0.1
            >>> print(IP('127.0.0.1'))
            127.0.0.1
            >>> print(IP('10'))
            10.0.0.0
        
        IPv6 addresses
        --------------
        
            >>> print(IP('1080:0:0:0:8:800:200C:417A'))
            1080::8:800:200c:417a
            >>> print(IP('1080::8:800:200C:417A'))
            1080::8:800:200c:417a
            >>> print(IP('::1'))
            ::1
            >>> print(IP('::13.1.68.3'))
            ::d01:4403
        
        Network mask and prefixes
        -------------------------
        
            >>> print(IP('127.0.0.0/8'))
            127.0.0.0/8
            >>> print(IP('127.0.0.0/255.0.0.0'))
            127.0.0.0/8
            >>> print(IP('127.0.0.0-127.255.255.255'))
            127.0.0.0/8
        
        
        Derive network address
        ===========================
        
        IPy can transform an IP address into a network address by applying the given
        netmask:
        >>> print(IP('127.0.0.1/255.0.0.0', make_net=True))
        127.0.0.0/8
        
        This can also be done for existing IP instances:
        >>> print(IP('127.0.0.1').make_net('255.0.0.0'))
        127.0.0.0/8
        
        
        Convert address to string
        =========================
        
        Nearly all class methods which return a string have an optional
        parameter 'wantprefixlen' which controls if the prefixlen or netmask
        is printed. Per default the prefilen is always shown if the network
        contains more than one address::
        
            wantprefixlen == 0 / None     don't return anything   1.2.3.0
            wantprefixlen == 1            /prefix                 1.2.3.0/24
            wantprefixlen == 2            /netmask                1.2.3.0/255.255.255.0
            wantprefixlen == 3            -lastip                 1.2.3.0-1.2.3.255
        
        You can also change the defaults on an per-object basis by fiddling with
        the class members:
        
         * NoPrefixForSingleIp
         * WantPrefixLen
        
        Examples of string conversions:
        
            >>> IP('10.0.0.0/32').strNormal()
            '10.0.0.0'
            >>> IP('10.0.0.0/24').strNormal()
            '10.0.0.0/24'
            >>> IP('10.0.0.0/24').strNormal(0)
            '10.0.0.0'
            >>> IP('10.0.0.0/24').strNormal(1)
            '10.0.0.0/24'
            >>> IP('10.0.0.0/24').strNormal(2)
            '10.0.0.0/255.255.255.0'
            >>> IP('10.0.0.0/24').strNormal(3)
            '10.0.0.0-10.0.0.255'
            >>> ip = IP('10.0.0.0')
            >>> print(ip)
            10.0.0.0
            >>> ip.NoPrefixForSingleIp = None
            >>> print(ip)
            10.0.0.0/32
            >>> ip.WantPrefixLen = 3
            >>> print(ip)
            10.0.0.0-10.0.0.0
        
        Work with multiple networks
        ===========================
        
        Simple addition of neighboring netblocks that can be aggregated will yield
        a parent network of both, but more complex range mapping and aggregation
        requires is available with the IPSet class which will hold any number of
        unique address ranges and will aggregate overlapping ranges.
        
            >>> from IPy import IP, IPSet
            >>> IP('10.0.0.0/22') - IP('10.0.2.0/24')
            IPSet([IP('10.0.0.0/23'), IP('10.0.3.0/24')])
            >>> IPSet([IP('10.0.0.0/23'), IP('10.0.3.0/24'), IP('10.0.2.0/24')])
            IPSet([IP('10.0.0.0/22')])
            >>> s = IPSet([IP('10.0.0.0/22')])
            >>> s.add(IP('192.168.1.0/29'))
            >>> s
            IPSet([IP('10.0.0.0/22'), IP('192.168.1.0/29')])
            >>> s.discard(IP('192.168.1.2'))
            >>> s
            IPSet([IP('10.0.0.0/22'), IP('192.168.1.0/31'), IP('192.168.1.3'), IP('192.168.1.4/30')])

        What's new
        ==========
        
        Version 0.81 (2013-04-08)
         * Correct reverseName() for IPv6 addresses, so IP('::1').reverseName() returns correct.
         * Add network mask awareness to v46map()
         * Fix Python 3 errors in IPSet class
         * Make IPSet base class be object when MutableSet isn't available, fixing
           errors in Python 2.5
        
        Version 0.80 (2013-03-26)
        ------------
        
         * Drop support of Python older than 2.4
         * Python 3 does not need 2to3 conversion anymore (same code base)
         * Fix adding of non-adjacent networks:
           192.168.0.0/24 + 192.168.255.0/24 made 192.168.0.0/23
         * Fix adding networks that don't create a valid subnet:
           192.168.1.0/24 + 192.168.2.0/24 made 192.168.1.0/23
         * Fix adding with an IPv6 address where .int() was < 32 bits made IPy believe it
          was an IPv4 address:
          ::ffff:0/112 + ::1:0:0/112 made 255.255.0.0/111
         * Add support of IPSets
         * Add support for subtracting a network range
         * Prevent IPv4 and IPv6 ranges from saying they contain each other
         * Add a .v46map() method to convert mapped address ranges
           such as IP('::ffff:192.168.1.1'); RFC 4291
         * Change sort order to more natural: 
           IPv4 before IPv6; less-specific prefixes first (/0 before /32)
        
        
        Version 0.76 (2013-03-19)
        -------------------------
        
         * ip == other and ip != other doesn't fail with an exception anymore if other
          is not a IP object
         * Add IP.get_mac() method: get the 802.3 MAC address from IPv6 RFC 2464
          address.
         * Fix IP('::/0')[0]: return an IPv6 instead of an IPv4 address
        
        Version 0.75 (2011-04-12)
        -------------------------
        
         * IP('::/0').netmask() gives IP('::') instead of IP('0.0.0.0')
        
        Version 0.74 (2011-02-16)
        -------------------------
        
         * Fix tests for Python 3.1 and 3.2
         * ip.__nonzero__() and (ipa in ipb) return a bool instead of 0 or 1
         * IP('0.0.0.0/0') + IP('0.0.0.0/0') raises an error, fix written by Arfrever
        
        Version 0.73 (2011-02-15)
        -------------------------
        
         * Support Python 3: setup.py runs 2to3
         * Update the ranges for IPv6 IPs
         * Fix reverseName() and reverseNames() for IPv4 in IPv6 addresses
         * Drop support of Python < 2.5
        
        Version 0.72 (2010-11-23)
        -------------------------
        
         * Include examples and MANIFEST.in in source build (add them to
           MANIFEST.in)
         * Remove __rcsid__ constant from IPy module
        
        Version 0.71 (2010-10-01)
        -------------------------
        
         * Use xrange() instead of range()
         * Use isinstance(x, int) instead of type(x) == types.IntType
         * Prepare support of Python3 (use integer division: x // y)
         * Fix IP(long) constructor: ensure that the address is not too large
         * Constructor raise a TypeError if the type is not int, long,
           str or unicode
         * 223.0.0.0/8 is now public (belongs to APNIC)
        
        Version 0.70 (2009-10-29)
        -------------------------
        
         * New "major" version because it may break compatibility
         * Fix __cmp__(): IP('0.0.0.0/0') and IP('0.0.0.0') are not equal
         * Fix IP.net() of the network "::/0": "::" instead of "0.0.0.0".
           IPy 0.63 should fix this bug, but it wasn't.
        
        Version 0.64 (2009-08-19)
        -------------------------
        
         * Create MANIFEST.in to fix setup.py bdist_rpm, fix by Robert Nickel
        
        Version 0.63 (2009-06-23)
        -------------------------
        
         * Fix formatting of "IPv4 in IPv6" network, eg. IP('::ffff:192.168.10.0/120'),
           the netmask ("/120" in the example) was missing!
        
        Version 0.62 (2008-07-15)
        -------------------------
        
         * Fix reverse DNS of IPv6 address: use ".ip6.arpa." suffix instead of
           deprecated ".ip6.int." suffix
        
        Version 0.61 (2008-06-12)
        -------------------------
        
         * Patch from Aras Vaichas allowing the [-1] operator
           to work with an IP object of size 1.
        
        Version 0.60 (2008-05-16)
        -------------------------
        
         * strCompressed() formats '::ffff:a.b.c.d' correctly
         * Use strCompressed() instead of strFullsize() to format IP addresses,
           ouput is smarter with IPv6 address
         * Remove check_addr_prefixlen because it generates invalid IP address
