*BUT* if you are using a relay with separate address spaces, this will not work (the client will not receive the reply), as explained below:
Note very carefully that a DHCPv4 server will send replies directly to a DHCPv4 client by way of 'ciaddr' even if the DHCPINFORM message was relayed. Note that this means DHCPINFORM processing is intentionally broken in deployments where the client's address space is unreachable by the DHCPv4 server.
(seehttps://tools.ietf.org/html/draft-ietf-dhc-dhcpinform-clarify-06)
I understand this. My dhcp server has a full ip routing information about the network.
