   The client uses a Request message to populate IAs with addresses and
   obtain other configuration information. <BR>
   The client generates a transaction ID and inserts this value in the
   "transaction-id" field.<BR>
   The client places the identifier of the destination server in a
   Server Identifier option.<BR>
   The client MUST include a Client Identifier option to identify itself
   to the server.
