Configure IPv6 on ESXi with the DCUI

In most cases you will not use IPv6 for your ESXi Network and should disable it. However, if you would like to use IPv6 the steps are similar to the IPv4 configuration.

Log into the DCUI by hitting the <F2> key and you will be prompted for the username and password. By default, the ROOT user is the default account. We will get into adding and changing the users with access to the DCUI as we harden the system.

Use your up/down arrows to navigate this menu.

Select Configure Management Network and press <ENTER>

Select IP IPv6 Configuration and press <ENTER>

Use your arrow keys select the desired IPv6 config. Best practice is to select Disable IPv6 (restart required) and press the <SPACE BAR>

Note: If you hit <ENTER> instead of <SPACE BAR> you will be brought back to the Configure Management Network screen and your changes will not be saved.

By default IPv6 is set to Use dynamic IPv6 address and network configuration. If you want ESXi to use DCHPv6 you must arrow down and select both Use dynamic IPv6 address and network configuration and Use DHCPv6, selecting each of the options using the
<SPACE BAR>

You can also set the IPv6 address statically by using your arrow keys to highlight Static IPv6 addresses and network configuration and press the <SPACE BAR>

Using your arrow keys to navigate, enter the IPv6 information specific to your environment for this host.

Once your changes are made and you press <ENTER> you will be returned to the Configure Management Network screen but the changes you just made will not appear until after a reboot.

Hit the <Esc> key and you will see a confirmation screen. Press <Y> to continue. Press <N> to return the network configuration to it’s original state, or <Esc> to continue making changes.
