I'm slowly updating my old applications to support IPv6, one of them simply refused to work with IPv6 without any obvious reason.
I discovered that winsock ReqVerHigh/ReqVerLow were being set to 1.1, whereas 2.2 is needed for IPv6. This turned out to be TWSocket components dropped onto three forms in the application which had saved 1.1 as design time properties but which never became updated as newer versions of TWSocket came along with 2.2. Updated the design properties and IPv6 now works. But very frustrating finding the issue.
