Summary Of DHCP Options / BOOTP Vendor Information Fields 1 DHCP Server General Implementation and Management Issues

The three preceding sections describe the DHCP address leasing system, configuration processes and messaging. Between them, these sections provide an explanation of all the fundamentals of the operation of DHCP. With this foundation in place, we can now proceed to look into some of the more interesting details of how DHCP is implemented. We can also delve into some of the extra capabilities and special features that change the basic DHCP mechanisms we have already studied.

In this section, I discuss DHCP client/server implementation issues, special features that enhance the protocol, and some of the problems and issues related to making DHCP work. I begin with a discussion of DHCP server and client implementation and management issues. I discuss DHCP message relaying and how it is related to the relaying feature used for BOOTP. I describe the DHCP feature for providing automatic default addressing when a client cannot contact a server, and the conflict detection feature for multiple servers. I then cover some of the issues related to interoperability of DHCP and BOOTP, and provide an outline of some of the more important problems and issues related to DHCP security.
