IP Address Management Principles and Practice (Hardcover)

This book will be the first covering the subject of IP address management (IPAM). The practice of IPAM includes the application of network management disciplines to IP address space and associated network services, namely DHCP (Dynamic Host Configuration Protocol) and DNS (Domain Name System). The consequence of inaccurately configuring DHCP is that end users may not be able to obtain IP addresses to access the network. Without proper DNS configuration, usability of the network will greatly suffer as the name-to-address lookup process may fail. Imagine having to navigate to a website or send an email or an instant message by IP address instead of by name! It's equally important that these DHCP and DNS configurations be based on a common IP address plan, which maps out the IP address hierarchy, subnets, address pools, and domains.

IPAM applies management disciplines to these core services, including configuration, change control, auditing, reporting and so on, and they are necessary given the absolute requirement for properly managing IP space and DHCP and DNS servers. The linkages among an IP address plan, DHCP server configuration and DNS server configuration are inseparable; a change of an IP address will affect DNS information and perhaps DHCP as well. These functions provide the foundation for today's converged services IP networks, so they need to be managed using a rigorous approach.

Today, there is no single book that covers the management of these linkages and services they provide; IP Address Management Principles and Practice will fill that gap. While several books are available for leading vendors' DHCP and DNS services implementations, few exist for IP address planning, and none exist that unifies these three topics.

這本書將是第一本涵蓋IP位址管理（IPAM）主題的書籍。IPAM的實踐包括將網絡管理學科應用於IP位址空間和相關的網絡服務，即動態主機配置協議（DHCP）和域名系統（DNS）。不正確配置DHCP的後果是終端用戶可能無法獲取IP位址以訪問網絡。如果DNS配置不正確，網絡的可用性將大大受到影響，因為名稱到位址的查找過程可能會失敗。想像一下，必須通過IP位址而不是通過名稱來導航到網站、發送電子郵件或即時消息！同樣重要的是，這些DHCP和DNS配置必須基於一個共同的IP位址計劃，該計劃對IP位址層次結構、子網、位址池和域進行了映射。

IPAM將這些核心服務應用於管理學科，包括配置、變更控制、審計、報告等等，這些都是必要的，因為正確管理IP空間、DHCP和DNS服務器是絕對必要的。IP位址計劃、DHCP服務器配置和DNS服務器配置之間的聯繫是不可分割的；更改IP位址將影響DNS信息，可能還會影響DHCP。這些功能為當今的統一服務IP網絡奠定了基礎，因此需要使用嚴謹的方法進行管理。

目前，還沒有一本書涵蓋了這些聯繫和它們提供的服務的管理；《IP位址管理原則與實踐》將填補這一空白。雖然有幾本書針對領先供應商的DHCP和DNS服務實施進行了介紹，但很少有書籍專注於IP位址規劃，而且沒有一本書能夠統一這三個主題。
