vSphere supports both Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) environments.

The Internet Engineering Task Force has designated IPv6 as the successor to IPv4. The adoption of IPv6, both as a standalone protocol and in a mixed environment with IPv4, is rapidly increasing. With IPv6, you can use vSphere features in an IPv6 environment.

A major difference between IPv4 and IPv6 is address length. IPv6 uses a 128-bit address rather than the 32-bit addresses used by IPv4. This helps alleviate the problem of address exhaustion that is present with IPv4 and eliminates the need for network address translation (NAT). Other notable 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.

An IPv6-specific configuration in vSphere involves providing IPv6 addresses, either by entering static addresses or by using an automatic address configuration scheme for all relevant vSphere networking interfaces.
