- "server interal address" represents the IPv4 address as a dotted quad to
be used by clients with the same external IP address as the server.
NOTE: In the PROTMESSID_CLM_SERVER_LIST list, this field will be empty
as only the initial IP address should be used by the client. Where
necessary, that value will contain the server internal address.
