Horizon 7 supports IPv6 as an alternative to IPv4. The environment must be either IPv6 only or IPv4 only. Horizon 7 does not support a mixed IPv6 and IPv4 environment.
Not all Horizon 7 features that are supported in an IPv4 environment are supported in an IPv6 environment. Horizon 7 does not support upgrading from an IPv4 environment to an IPv6 environment. Also, Horizon 7 does not support migration between IPv4 and IPv6 environments.
