OK, since you've asked, here is an example -- please note that having a
separate section
which eliminates the confusion between "representation" and
"partitioning" would IMHO add clarity:
----------
X.Y. Address Space Partitioning
The IPv6 address space is partitioned to provide an adequate number of
addresses for various types of communications, such as unicast,
multicast, and/or anycast. The partitioning provides also an adequate
number of addresses for experimental, and/or future use.
Currently the following space is partitioned and assigned for:
IPv6 unicast:
1/1024 (2**118 = 332306998946228968225951765070086000 addresses) of the
total space is assigned for link-local communications
1/1024 (2**118 = 332306998946228968225951765070086000 addresses) of the
total space is assigned for site-local communications
1/8 (2**125 = 4.2535295865117307932921825928971e+37 addresses) of the
total space is assigned for global unicast communications
note: anycast communications used unicast address space
IPv6 multicast:
1/256 (2**120 = 1.3292279957849158729038070602803e+36 addresses) of the
total space is assigned for multicast communications
RFC 1888:
1/128 (2**121 = 2.6584559915698317458076141205607e+36 addresses) of the
total space is
assigned for RFC 1888 type communications
This represents 1/8+7/512 of the total IPv6 address space.
Unassigned:
6/8 + 57/512 (2.5521177519070384759753095557382e+38
+ 3.788299787987010237775850121799e+37
of addresses)
This is the remaining of the address space, which has not
been assigned.
Note: specifying real numbers along with fractions adds a good
indication of the dimensions of the address space.
