The MOVeable DISTRUPTive parameter is not supported for IPv6. To prevent an unauthorized application from creating a dynamic VIPA with a bind() call, you can add the EZB.BINDDVIPARANGE.sysname.tcpname resource profile, or you can use the SAF parameter along with the EZB.BINDDVIPARANGE.sysname.tcpname.resname resource profile. If the security check fails, the bind() request fails, and if the security check is successful, the bind() request is accepted.
