Hi Siva,
See RFC 3513:
2. IPv6 Addressing
(...)
There are no broadcast
addresses in IPv6, their function being
superseded by multicast
addresses.
2.4 Address Type
Identification
The type of an IPv6 address is
identified by the high-order bits of
the address, as
follows:
Address
type Binary
prefix IPv6 notation
Section
------------
-------------
------------- -------
Unspecified 00...0
(128 bits)
::/128
2.5.2
Loopback
00...1 (128 bits)
::1/128 2.5.3
Multicast
11111111
FF00::/8 2.7
Link-local unicast
1111111010
FE80::/10 2.5.6
Site-local
unicast
1111111011
FEC0::/10 2.5.6
Global

Anycast addresses are taken
from the unicast address spaces (of any
scope) and are not
syntactically distinguishable from unicast
addresses.
