IPv6 address scheme for a local area network

AIM: To plan IPv6 address scheme for a local area network consisting of ‘n’ terminals.

One of the main benefits of Internet Protocol version 6 (IPv6) over previously used internet protocol version 4 (IPv4) is the large address-space that contains (addressing) information to route packets for the next generation Internet. IPv6 supports 128-bit address space and can potentially support 2128 or 3.4W1038 unique IP addresses (as opposed to 32-bit address space of IPv4). With this large address-space scheme,IPv6 has the capability to provide unique addresses to each and every device or node attached to the Internet.

To configure an Ethernet line description for IPv6, you must use the IPv6 Configuration wizard iniSeries Navigator. IPv6 may only be configured from iSeries Navigator, and may not be configured from the character-based interface. The wizard requires the name of the hardware communications resource on the server on which you will configure IPv6; for example, CMN01.

This must be either a 2838 or 2849 Ethernet adapter that is not currently configured for IPv4.

To use the IPv6 Configuration wizard, follow these steps:

1. In iSeries Navigator, select your server ––> Network ––> TCP/IP Configuration.
2. Right-click IPv6, select IPv6 Configuration, and follow the wizard’s instructions to configure an Ethernet line for IPv6.Configure ipv6 in windows 7 steps.

Windows 7 enables IPv6 by default. Should your IPv6 connection not automatically work, try:

1. Right-click the Wi-Fi icon in the system tray and open Network and Sharing Center.
2. Click on the adapter you are using to get a Status window.
3. Click on Properties.
4. Select Internet Protocol Version 6 (TCP/IP) and choose Properties.
5. Choose “Obtain an IPv6 address automatically.”
6. Press OK and then close out of the Properties and Network and Sharing Center.
