Hello group, I have a nagging question about how the DHCP server assigns an IP address to a DHCP client from the correct pool of addresses. Let me give a scenario so that you understand my concerns. A host called Subnet_A _Client sends a dhcp request. The router's interface on subnet A is Ethernet_A. The router sends the dhcp request to subnet B, where the DHCP server resides. The router's interface on subnet B is Ethernet_B. My question is how will the DHCP server know that the dhcp request is coming from subnet A? Will the DHCP server unicast or broadcast the dhcp reply? To which address will the server unicast its dhcp reply? If someone can help me or refer me to a good online document that will answer my questions, I will appreciate it.
