Dynamic Host Configuration Protocol (DHCP) provides a means of allocating and managing IP addresses dynamically over a network. Before the advent of DHCP, administrators configured each host on a network with an IP address, subnet mask, and default gateway. Maintaining the changes and the logs of the changes took a tremendous amount of time and was prone to error. DHCP uses a client/server model in which the network information is maintained and updated dynamically by the system.
This book discusses DHCP in a Windows 2000 environment. It provides an introduction to the DHCP protocol and shows how to implement a DHCP server into the network. It also covers the more advanced features of DHCP.
The book begins with an overview of the TCP/IP protocol suite and shows how DHCP coexists with the rest of the TCP/IP suite. It identifies DHCP's predecessors, RARP and BOOTP, and explores the reasons that DHCP was developed. DHCP design considerations are discussed, as well as the different methods of deployment. The book shows how to install and configure DHCP servers in routed and non-routed environments and how to configure a client to use DHCP. It also discusses how to administer a DHCP server in Windows 2000 using DHCP scopes, options, and leases. Finally, the book covers DHCP's close relationship with Dynamic DNS, as well as some of the future directions for DHCP.
Topics covered: The Dynamic Host Configuration Protocol (DHCP), as implemented by Microsoft Windows 2000 on the server side and other Microsoft operating systems (including MS-DOS) on the client side. Chapters address (pun intended) basic configuration scenarios, as well as scopes, superscopes, multihomed DHCP servers, and clustering. For those for whom DHCP won't do, there's a section on multicast configuration with Multicast Address Dynamic Client Allocation Protocol (MADCAP) under Windows 2000.
Dynamic Host Configuration Protocol (DHCP) is an open standard Internet protocol used to allocate and manage IP addresses dynamically. Before DHCP came along, administrators had to manually configure each host on a network with an IP address, subnet mask, and default gateway. Maintaining the changes and the associated logs took a tremendous amount of time and was prone to error. DHCP uses a client/server model in which the system updates and maintains the network information dynamically. Windows 2000 provides enhanced DHCP client-server support. DHCP for Windows 2000 is custom-designed for system administrators who are responsible for configuring and maintaining networks with Windows 2000 servers. It explains the DHCP protocol and how to install and manage DHCP on both servers and clients--including client platforms other than Windows 2000. Readers get detailed and explicit instructions for using Windows 2000 DHCP to manage their network IP configurations much more efficiently and effectively.They get background information for using DHCP in general, plus complete information about the Windows 2000 use of DHCP. For those interested in what's on the horizon, the author steps up to the plate with an analysis of the future direction of DHCP and Windows support for IPv6.
