(Plz. let me know if this is wrong list to ask this ques.)
Following is the part from handbook/ipv6.html
------ BEGIN ----
19.14.2 Reading IPv6 Addresses
The canonical form is represented as: x:x:x:x:x:x:x:x, each
``x'' being a 16 Bit hex value. For example
FEBC:A574:382B:23C1:AA49:4592:4EFE:9982
Often an address will have long substrings of all zeros
therefore each such substring can be abbreviated by ``::''.
For example fe80::1 corresponds to the canonical form
fe80:0000:0000:0000:0000:0000:0000:0001
A third form is to write the last 32 Bit part in the well known (decimal) IPv4 style with dots ``.'' as separators.
For example 2002::10.0.0.1 corresponds to the (hexadecimal) canonical representation
^^^^^^^^^^^^^^
2002:0000:0000:0000:0000:0000:000a:0001 which in turn is equivalent to writing
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2002::a:1
By now the reader should be able to understand the
following:
# ifconfig
rl0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
inet 10.0.0.10 netmask 0xffffff00 broadcast 10.0.0.255
inet6 fe80::200:21ff:fe03:8e1%rl0 prefixlen 64 scopeid 0x1
ether 00:00:21:03:08:e1
media: Ethernet autoselect (100baseTX )
status: active
fe80::200:21ff:fe03:8e1%rl0 is an auto configured link-local
address. It includes the enscrambled Ethernet MAC as part of
the auto configuration.
For further information on the structure of IPv6 addresses
see RFC2373
----- END ----
As far as I can understand,
2002:10.0.0.1 should be 2002:0000:0000:0000:0000:0000:0a00:0001
i.e. 2002::a00:1 and not 2002::a:1
