4 Plan Your IPv6 Implementation
This section provides ideas for planning your IPv6 implementation.
Obtain IPv6 Addresses
IPv6 addresses are now being deployed by the regional registries. To obtain an IPv6
address or block of addresses, contact your Internet Service Provider (ISP).
If you are an Internet Service Provider, contact your upstream registry or one of the
registries at these locations:

APNIC (Asia-Pacific Network Information Center)

ARIN (American Registry for Internet Numbers)

RIPE NCC (Réseau IP Européens)
As various implementations of the IPv6 RFCs must be tested, the Internet Engineering
Task Force (IETF) has defined a temporary IPv6 address allocation scheme. You can
assign the addresses in this scheme to hosts and routers for testing IPv6 on the
6bone. For more information on 6bone address allocation and assignment, see the
6bone home page at this location:
http://www.6bone.net
After you contract with your ISP for a block of addresses, your deployment of IPv6 in
your network begins the process of renumbering of your network. In IPv6, network
renumbering is somewhat dynamic so you can renumber your network for any of these
reasons:

Your enterprise is growing and needs more address space.

Your network needs are changing.

Your enterprise wants a global presence.

You are outgrowing your ISP.
Whatever the reason, when your current ISP contract expires, your right to use the
block of IPv6 addresses also expires. Use these guidelines to help you with
renumbering:

Have your routers advertise new network prefixes and deprecate the old prefixes
by setting a lifetime.

Change DNS servers to advertise node names and the new addresses.

Do not hard code addresses in configuration files because hard coding makes the
process more complex and labor intensive.

Clear all server caches as appropriate.
