隨著網絡規(guī)模的日益擴大以及人們對網絡的移動性的要求越來越高，如果仍采用靜態(tài)地址分配的方法進行IP管理，會給用戶帶來諸多不便，也給網絡管理員增加很多工作量。采用動態(tài)主機配置技術進行IP管理、可以很好地解決這些問題。文章簡要地介紹了DHCP技術的工作原理，以及DHCP技術在工業(yè)以太網中的應用。實踐表明，DHCP技術對管理大規(guī)模的以及對網絡移動性要求高的網絡系統具有重要的意義。

Abstract: With the rapid expansion of the network scale and increasing requirement to network mobility, users will encounter several difficulties if traditional static address assignment is still adopted in IP management, and network manager will bear heavier load. IP management by Dynamic Host Configuration Protocol can commendably solve these problems. This paper presents the principle of DHCP technique and its application in Industrial Ethernet. It shows the significance of DHCP application on management of large-scale networks and on the network systems that require high mobility.
