Configuration of IPv6 address for dedicated server

Dedicated server from WebSupport allows except the public IPv4 address setting also the use of IPv6 address, that needs to be configured manually as static.

For services Virtual server (VPS) and Virtual data center (VDC) are all IP addresses assigned dynamically with DHCP.
