The V6 flag indicates that the application that the member refers to has set the IPV6_V6ONLY socket option. This socket option disallows connections to the server application using an IPv4 address as the destination IP address when the server application has bound to the IPv6 unspecified address (in6addr_any). If a member is coded with an IPv4 address and intends to represent an application that has the IPV6_V6ONLY socket option set, the member will not be available for workload balancing and the V6 flag is displayed for this member. Conversely, for any member that represents this target application and is coded with an IPv6 address that can be used to reach the target application, the member will be available for workload balancing and the V6 flag is displayed. Line 22 in Figure 1 shows an example of this flag. For more information on the V6 flag, see z/OS Communications Server: IP System Administrator's Commands.
