Server: Added IPv6 support for all DNS Providers, but only tested ISC BIND & MS DNS Enterprise Server: Added support for IPv6. Hyper-V not tested, and probably doesn't work. When using IPv6 with Hyper-V it assigns "/CIDR" to the subnet mask, and I don't know if this is the correct implementation. Portal: Modified all IP input masks to accept and validate IPv6. IP Ranges support IP/CIDR format.
