When the user selects TCP/IP, the FairCom build system now defaults to enabling IPv6 instead of only IPv4. This change makes this Internet protocol available by default to ensure your applications have support for the latest standards.
To begin using IPv6 support, you must enable the TCP/IP communication protocol support on the FairCom DB Server side by making sure this keyword is enabled in ctsrvr.cfg:
COMM_PROTOCOL F_TCPIPV6
It is possible to have both IPv4 and IPv6 support enabled at the same time.
