openvpn server can push dhcp-option DNS6, in which case the openvpn-update-resolv-conf script will ignore it, since it expects "DNS" string only.

Overview of changes in 2.4

Support for providing IPv6 DNS servers

    A new DHCP sub-option DNS6 is added alongside with the already existing DNS sub-option. This is used to provide DNS resolvers available over IPv6. This may be pushed to clients where `` --up`` scripts and --plugin can act upon it through the foreign_option_<n> environment variables.

    Support for the Windows client picking up this new sub-option is added, however IPv6 DNS resolvers need to be configured via netsh which requires administrator privileges unless the new interactive services on Windows is being used. If the interactive service is used, this service will execute netsh in the background with the proper privileges.
