DHCP Setup Notes

Items

• BOOTP - Bootstrap Protocol (BOOTP) is a host configuration protocol that DHCP is based on. In this protocol MAC addresses are used to identify clients where they are assigned specific IP addresses. What differentiates it from DHCP is BOOTP does not have dynamic address assignment, meaning each client must be identified in a limited amount of config information in the configuration.

• Lease - The lease in DHCP is the amount of time in which a client holds IP address information, when expired the client must renew it.

• Relay - The relay is a router/host that listens for broadcasted client messages on the network an proceeds to forward them to a server. This server will then send responses back through the relay, who will then pass them along to the client. This can be used to centralize servers used for DHCP.
