[Environment Variable] COREDX_IP_ADDR [Values] Valid, Local IP address [Description] 
As part of discovery, each DDS DomainParticipant advertises local IP addresses that peers can use to communicate with it. If your machine has multiple network interfaces, CoreDX DDS will by default advertise (and use) all interfaces for DDS communications. This may generate unnecessary network traffic on some of those networks. This environment variable will limit DDS traffic to just one interface - the interfaces specified by the IP address.
