IPV4 is currently the world's most widely used second-generation http://www.aliyun.com/zixun/aggregation/5739.html "> Internet technology, but it is facing the network Address resource shortage crisis." The August 2011 Internet numbering Agency (IANA) has allocated the last 5 IPv4 addresses to the five regional registrars, which means that the IPV4 address pool has been allocated. In the international context, some companies will gradually find that they have been unable to obtain from the operator 920.html "" "Enterprise development needs of the IPV4 address.
Although many operators and enterprises have already had a lot of IPv4 before IPv4 distribution, and there is a lot of optimization space for the future IPV4 allocation strategy of the operators, but as the best response of insufficient network address resources, the IPV6 technology should be paid more and more attention. Now, more and more enterprises are engaged in the development of IPV6, more and more hardware and software is designed to support IPV6, its many advantages such as large address space, message head format flexible, fast processing, high security, support more service types will be more used by the industry in the future. Of course, due to the current IPv4 still occupy the dominant position, so in the future for a long time there will be IPv4 and IPv6 coexistence situation.
IBM has also been in the development of IPV6 to make a difference, more and more products have been supporting IPV6. As a centralized management software Bae Director also started to support IPV6 as early as the 6.2 version in 2010.
BAE Director about IPV6 support
As a support IPV6 application, IBM Bae Director supports discovering (IPV6) and managing terminal resources through IPV4 or discover. Bae Director is a software application that does not directly implement the IP stack, but is implemented using the operating system of the Director Server itself and the terminal managed host. Table 1 shows the support for the IPv6 of IBM Bae Director Server and managed terminal resources.

If IPv4 and IPV6 are already configured on the Director server side, Director server can manage a pure IPV6 terminal or manage terminals configured with two stacks. However, if the management is configured with a dual-stack terminal, even if the IPV6 protocol is used to discover (discover) terminals, when Director server recognizes that terminal devices also support the IPV4 protocol, Director server will be given priority over IPV4 management.
We will then introduce two examples. The first is a dual stack of Director Server management is also equipped with a dual-stack terminal. Here we will use the IPV6 protocol to discover (discover) terminals. The second is the Director Server management with separate IPv6 with a separate IPV6 terminal. Both of these examples are based on the AIX operating system.

Director server-side IPV6 configuration
In general, IPV4 already exists, assuming that Director Server 6.3 is already installed on AIX6.1.
Figure 1.Director Server AIX 6.1 IPv4 Configuration
Here is the static IPV4 address.
A static IPv6 and IPV6 route is assigned to the operating system.
#chdev-L en0-a netaddr6= ' fd55:faaf:e1ab:1b09:10:10:12:64 '-a prefixlen= '-a state=up #chdev-l inet0-a rout6=net,,,, , ' Default ', ' fd55:faaf:e1ab:1b09:10:10:12:64 '

Then restart the Director Server's operating system for the configuration to take effect correctly.
