1. Introduction to DHCP Service DHCP is Dynamic host Configuration Protocol, which is a way to assign IP addresses to hosts in a physical network, distinguishing them from BOOTP, and assigning a lifetime use disadvantage. The concept of a DHCP-proposed lease makes it possible to dynamically determine the IP address r

DHCP is based on the customer/Server mode. When the DHCP Client is started, it automatically communicates with the DHCP server, and the DHCP server provides services with automatically assigned IP addresses for the DHCP client. The server where the

that a new IP address is automatically received when a computer moves to another location in the network. However, although DHCP looks "beautiful" and is easy to implement, problems still occur when configuring applications. Once I migrated the DHCP server, I found that the DHCP server has been closed, but some clients that use the automatically obtained IP Addr

Configuring TCP/IP clients manually in addition to being a time-consuming chore, setting errors can also cause network communication failures. DHCP avoids these errors and provides many other advantages, including automatic assignment of the new address of the computer from one subnet to another, and automatic recycling when not in use.The process of DHCP configuration:650) this.width=650; "Title=" Drawing

Introduction to DHCP services 　 DHCP is based on the customer/Server mode. When the

clear that there cannot be any other DHCP server providing IP addresses to the relay, for two reasons: the first reason is that the relay device explicitly instructs the DHCP server to which it applies for an IP address. The second reason is that when the relay initiates a DHCP Discover message, it is sent by unicast, there will be no second

The address pool in the DHCP server is organized in a "Tree" structure. The root is the address of the natural CIDR block. Each branch is the subnet address of the CIDR block, and the leaf node is the client address manually bound. This tree structure achieves configuration inheritance, that is, the subnet (son node) configuration inherits the configuration of the natural network segment (parent node), each client (Sun Tzu node) the configuration also

Experimental environment: the company's internal network is divided into three physical network segments, and each other is connected through a Linux gateway server. To provide centralized Address Allocation management, we need to build a DHCP server without increasing hardware investment, dynamically configure network parameters such as IP addresses for clients in different network segments (the experiment topology is as follows): Requirement Descrip
