The IPv6 support in vSphere lets hosts work in an IPv6 network that has a very large address space, enhanced multicasting, simplified routing, and so on.

About this task

IPv6 is designated by the Internet Engineering Task Force as the successor to IPv4. The most obvious advantage of IPv6 to IPv4 is address length. IPv6 uses 128-bit addresses rather than the 32-bit addresses used by IPv4. This increase resolves the problem of address exhaustion and eliminates the need for network address translation. Other differences include link-local addresses that appear as the interface is initialized, addresses that are set by router advertisements, and the ability to have multiple IPv6 addresses on an interface.

In ESXi 5.1 and later releases, IPv6 is enabled by default.


Required privilege: Host > Configuration > Network > Configuration.


  1. In the vSphere Web Client, navigate to the host.
  2. On the Manage tab, click Networking and select Advanced.
  3. Click Edit.
  4. From the IPv6 support drop-down menu, enable or disable IPv6 support.
  5. Click OK.
  6. Reboot the host to apply the changes in the IPv6 support.

What to do next

Configure the IPv6 settings of VMkernel adapters, for example, of the management network. See Edit a VMkernel Adapter Configuration in the vSphere Web Client.
