Book Description
Editorial Reviews
From the Inside Flap
Preface
This book explains the Dynamic Host Configuration Protocol (DHCP). DHCP allows computers to be configured, in the best case, by merely plugging them in and turning them on. At the appropriate point in the boot sequence, the newly connected computer will search for a DHCP server and negotiate with it for an IP address and other configuration parameters such as DNS server addresses, default routers, and a host of other parameters.
How all this works is the subject of this book.
After a high-level introduction, we'll take a look at the BOOTP protocol in Chapter 2, which is the foundation on which DHCP was built.
The DHCP protocol itself is described in Chapter 3, followed by a detailed look at operations from the client and server points of view in Chapters 4 and 5, respectively.
Chapter 6 discusses the relay agents that allow one DHCP server to manage addresses on more than one subnet at a time, and Chapter 7 describes how DHCP can update DNS with correct information as it hands out addresses.
Chapter 8 describes the administration side of DHCP, with some detail about popular servers.
The rest of the book is oriented toward the future. Chapter 9 is about the forthcoming integration of DHCP with directory services, specifically LDAP, and Chapter 10 is about the new version of DHCP that will support IPv6.
Chapter 11 finishes off with a look at what's going on in the IETF working group.
An appendix on DHCP software and one with the principal RFCs describing the protocol wraps up the book, along with a glossary and index. Note on Language
You will notice that terms like "BOOTP" include the term "protocol" as the "P", yet the usage "BOOTP protocol" is frequent. To a language purist, this can be as annoying as "ATM Machine" or "PIN Number". I beg your indulgence with the explanation that in this book, and indeed in the networking community, terms like "BOOTP" or "DHCP" have come to mean more than just the protocols. They include systems, programs, databases, back-ends, front-ends, user interfaces — in short, the entire system. When I wish to refer specifically to the protocol aspect of, say, DHCP, I will say "DHCP protocol".
In addition, I've tried to be gender-neutral, but probably haven't completely succeeded; I have no wish to offend anyone and hope this advance apology will suffice if I inadvertently do. Internet Draft Notice
Sometimes I refer to Internet Drafts which are both the most current source of Internet information and the most unstable. Here is the warning attached to every Internet Draft:
Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress." To learn the current status of any Internet-Draft, please check the "1id-abstracts.txt" listing contained in the Internet-Drafts Shadow Directories on ftp.is.co.za (Africa), nic.nordu (Europe), munnari.oz.au (Pacific Rim), ds.internic (US East Coast), or ftp.isi (US West Coast).
From the Back Cover
The definitive guide to connecting your LAN to the Internet with DHCP.
With DHCP, network administrators can automatically, remotely configure every desktop in the enterprise for Internet access. Now, there's a complete guide to DHCP--how it works, how to use it, and where it's headed. Networking expert Berry Kercheval starts with an exceptionally easy-to-understand explanation of this powerful protocol. You'll learn how DHCP works from both the client's and server's point of view. You'll master DHCP's multiple configuration options, and choose the right ones for your network. And if you're a developer, you'll learn all you need to start building DHCP-based solutions. Coverage includes:
* Dynamic DNS, including essential security techniques, and new options such as client FQDN.
* Techniques for administering DHCP, including subnet and lease maintenance.
* Integrating DHCP with LDAP, IPv6 and other key Internet-related protocols.
Whether you run NT, UNIX or both, DHCP: A Guide to Dynamic TCP/IP Network Configuration will help you make the most of DHCP, now and in the future. Kercheval previews the latest DHCP extensions and proposals, including Secure DHCP and Reliable DHCP. You'll also find a comprehensive vendor guide, including both free and commercial DHCP suppliers. This book also contains the complete DHCP RFC documents.
If you manage Internet access in the enterprise, you need the in-depth understanding of DHCP that only one book delivers; Berry Kercheval's DHCP: A Guide to Dynamic TCP/IP Network Configuration.

Great Content, Lousy Editor,
By A Customer
This review is from: DHCP: A Guide to Dynamic TCP/IP Network Configuration (Hardcover)
I purchased this book on the way to the airport in transit to yep, fixing a distributed DHCP server problem. I found a great deal of useful information in the book, and after having read the book, I am considered an expert among most mortals. The book successfully turns the RFCs on the subject into readable text, and liberal use of footnotes are there to explain some of the more esoteric notions, and shows packet formation, which is a valuable visual aid. Unfortunately, I also found an unacceptable number of editing errors. Kercheval (author) has done a very good job with presenting the information, but the editor missed a lot. The book was edited by Radia Perlman (says so on the back cover), and I have to say if I see his/her/its name on other books as editor, I'll have to pass. This book has a lot of usefulness in it, but the errors in editing are glaring if you know anything at all about networking. Normally, I wouldn't be too upset about typos, but in technical works one wrong character can change the entire meaning of whatever point is being made. My technical writing professor in college would have flunked this editor in a heartbeat. I forwarded a list of my concerns to both the author and the publisher. Kercheval was interested in them, the publisher did not fill my heart with warm fuzzies, or even acknowledge receipt. A simple "Thank You" would have been nice. A next edition with the corrections would be fantastic. If you want the guts of DHCP, and you need it now, go ahead and by this edition. If you can wait til Prentice Hall gets it right, then buy the next edition. Personally, if I were Kercheval, I'd be majorly P.O.ed... Can you sue a publisher for malpractice?

Where is the depth?,
By A Customer
This review is from: DHCP: A Guide to Dynamic TCP/IP Network Configuration (Hardcover)
This book gives a good overview of dhcp in the first 5 or 6 chapters but is definately not a "definitive guide". The trouble is I really felt a lot of detail was left out. After about page 60 (halfway thru the book if you dont count the appendices) things really started to get a bit light on detail. The SINGLE chapter on configuring dhcp servers covered how define multiple addresss ranges but seemed to skip the details of how to get the server to choose which range to allocate to a particular client. The chapters on DDNS and LDAP seemed to do little more than say what DDNS and LDAP are. I will say that the appendices do contain useful information (a list of the DHCP options and a copy of 4 key RFCs) but this is all information easily obtained over the internet. All in all I was disappointed with this book. It would have been a good $20-$25 intro book. It is not in my opinion a good buy if you are looking for a definitive guide.

NOT WORTH THE MONEY,
By A Customer
This review is from: DHCP: A Guide to Dynamic TCP/IP Network Configuration (Hardcover)
I bought this book in hopes in would help me understand dhcp for the mcse exams. Well, I was wrong. $45 down the drain. This book has no more information than any of the other tcp/ip books on the subject of dhcp. Dont let the dollar price fool you into thinking your getting a good book. Needless to say, I was very disappointed in this book.
