Understanding IPv6

Postby guest » Tue Oct 14, 2008 10:49 pm

The first 64 bits of the IPv6 address typically identifies your network or
"where you are" and the second 64 bits identifies the device or "who you
are."

For your question, you can refer to "Subnetting for IPv6" of this article:

I would like to explain more about IPv6 address and how to configure IPv6
address:
==================================================
There are four types of unicast IPv6 addresses.
1) Global addresses are equivalent to public IPv4 addresses and are used on
the IPv6 Internet.
2) Site-local addresses are equivalent to private IPv4 addresses and are
used within a single site of an organization. Site-local addresses have
been deprecated by the Internet Engineering Task Force but current
implementations of IPv6 can still use them.
3) Link-local addresses are equivalent to IPv4-based Automatic Private IP
Addressing (APIPA) addresses used in current Microsoft operating systems
and are used on a link.
4) Unique local addresses (also known as local addresses) are the
replacement for site-local addresses that provide addresses that are
private to an organization, but unique to the sites within the
organization.

Link-local addresses are automatically configured for each interface.
Global, site-local, and local addresses are automatically configured based
on the receipt of a Router Advertisement (RA) message that contains Prefix
Information options. IPv6 routers send RA messages.

By default, IPv6 configures link-local IPv6 addresses for each IPv6
interface. Link-local addresses have the prefix FE80::/64. Additional
global or unique local addresses might also be configured depending on
whether you have routers that are sending Router Advertisement messages.

[How to manually configure IPv6 address?]

For most hosts, you do not need to manually configure IPv6 addresses. In
addition to auto-configuring link-local addresses for all Ethernet
interfaces, the IPv6 protocol for Windows participates in router discovery
to discover the presence of local IPv6 or ISATAP routers and autoconfigure
additional IPv6 addresses. Router discovery requires a properly configured
IPv6 router on your network segment or an ISATAP router.

Without an IPv6 or ISATAP router, you can manually configure additional
IPv6 addresses on interfaces using the netsh interface ipv6 add address
command on computers running Windows. This command allows you to specify
the interface, the address, the preferred and valid lifetimes, and whether
the address is unicast or anycast. Manually configured addresses must be
reachable to communicate with other IPv6 nodes.
