Internet Protocol version 6 (IPv6) support in ESXi provides the ability to use Virtual Infrastructure features such as NFS in an IPv6 environment. Use the Networking Properties dialog box to enable or disable IPv6 support on the host.
IPv6 is designated by the Internet Engineering Task Force as the successor to IPv4. The most obvious difference 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 VMware ESXi 5.1, IPv6 is enabled by default.
