Write/Read IPv6 Addresses in Registry (Windows Vista-10) with Delphi -- 2

I'd like to be able to configure IPv6 addresses for local network interfaces from my Delphi application. Manually it's possible in the IPv6 properties in the Windows Network Connections context menu, or by using [login to view URL] ("netsh interface ipv6 add address"). [login to view URL] can be reverse engineered to find out how MS does it. On StackOverflow someone explains this: [login to view URL] So you basically only have to follow this path and complete the work. What I need: 1. function SetIpv6UnicastIps(NetworkAdapterId: String; IPs: TStringList): Boolean; This writes the given IPv6 addresses (incl. Subnetmask Prefix integer) to the Registry for the selected NIC (e.g. "{12345678-1234-1234-1234-123456789012}") in the correct form, so that after manually restarting the network adapter these addresses are used by that NIC. -> Result can be reviewed in the context menu of that NIC in the "Network Connections" dialog of Windows and in command line "ipconfig /all". 2. function GetIpv6UnicastIps(IPs: TStringList): Boolean; -> Get currently set IPs and add them to the stringlist parameter. Include the Subnetmask Prefix as an object for every stringlist item. Same for Gateway Metric. 3. Both Set & Get functions equivalently for Multicast, Anycast, Gateways (with Metric) and DNS. I will use your code in an existing project. Your UI is only for demonstration of your results. Requirements: 1. Must be Delphi code! Must be compilable in Delphi XE. DLLs or external command line tools are not acceptable. 2. Must work with Windows Vista, 7, 8.1, 10. (the solution is probably the same for all of them).
