The ipv6 support I'm referring to relates to code that allows the daemon to listen/bind to an ipv6 address. Clearly this cannot work on OS/2 as our tcpip stack is only ipv4. Nothing prevents the daemon on OS/2 returning an ipv6 address - although of course any ipv6 clients need to be requesting those addresses from an ipv4 daemon, so you couldn't use it in a pure ipv6 environment. Hope this makes sense..
