4. Deployment Considerations

This section preserves the RFC text for DHCPv4 over DHCPv6 with Relay Agent support, including relay behavior, topology-discovery diagrams, deployment notes, security considerations, and IANA status.

4.  Deployment Considerations

   As clients are unaware of the presence of 4o6RA, the network
   deployment needs to ensure that all DHCPv4 broadcast and unicast
   messages to and from clients are steered via a 4o6RA.  This can be
   achieved by placing the 4o6RA in a central position that can
   intercept all traffic from the clients or by using Network Address
   Translation (NAT) with the 4o6RA address for unicast messages.
