    Not possible to set IPv6 address as DNS server

    The version of Proxmox in concern is 3.4.11. I want to setup some IPv6 only OpenVZ containers where IPv4 is not available for CTs. I found it's not possible to put in IPv6 address as name server in the Proxmox web ui. Is there any way I can use IPv6 addresses as the CT's name servers?
