Summary
Yes (guests only)
Details
Guest VMs hosted on Citrix Hypervisor can use any combination of IPv4 and IPv6 configured addresses.

However, Citrix Hypervisor doesn’t support the use of IPv6 in its Control Domain (Dom0). You can’t use IPv6 for the host management network or the storage network. IPv4 must be available for the Citrix Hypervisor host to use.
