First, the basic concept of DHCP
Dhcp:dynamic host Configration Protocol Dynamic Host Configuration ProtocolC/S Architecture:Server: Static address. Provides a pool of addresses (list): 67/UDPClient: Dynamic address, 68/UDP (the server sometimes initiates a request to the client)DHCP scope of work: The current physical network can not be carried out across the network;
DHCP server configurationOne, what DHCP The DHCP (dynmaic Host configuration Protocol) server is used to provide network configuration information so that the DHCP guest in the networkThe system can dynamically receive the network parameter information and automatically realize the network configuration of the system.
Today, a slightly larger enterprise network typically uses a DHCP server to uniformly allocate TCP/IP configuration information to clients. This method not only reduces the maintenance workload of network administrators, but also improves the security of the Enterprise network. However, the security of the DHCP server is not negligible, it once the problem, it will affect the normal operation of the entire
School laboratory large and small equipment, network environment although not complex, but also more complex than the home. Just practice practiced hand, just write some articles, lest later the laboratory network no one tube. So let's start with the DHCP configuration!What 1.DHCP is. What's the use?Dhcp. Dynamic Host configuration Protocol. config protocol. is a
We all know that using DHCP to dynamically allocate IP addresses can reflect the ease of use, especially when there are many hosts in the LAN, it is a good choice to configure the DHCP server. In this article, we will implement the following DHCP goals: (1) Basic settings of scope (2) settings of host binding (3) Super scope settings (4) Server
We all know that u
We all know that DHCP is a service for IP address management. In some network changes, we also need to modify the settings. Here we will explain how to configure the multi-vlan dhcp service. All aspects must be taken into account when upgrading the network, and how to implement the DHCP service in a multi-VLAN environment is one of them.

DHCP introduction:
The original name of DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) is a LAN network protocol that uses UDP protocol for two purposes: an IP address is automatically assigned to an internal network or network service provider. The IP address is described in RFC 2131 as a central management method for all computers. DHC
We can use DHCP servers to manage a large network and a wide range of IP addresses. For example, the following is an example. In my company, the local area network of the sales department is growing and the number of clients increases sharply. donggua, a network manager of the sales department, wants to use the DHCP server to dynamically allocate IP addresses to avoid the trouble of manually assigning IP ad
An important part of DHCP settings is DHCP option settings. In this regard, let's talk about it in detail separately. In addition to providing IP addresses for DHCP clients, the DHCP server can also set the working environment when the DHCP Client is started, for example, yo
We have learned about dhcp relay and explained in detail the setting of each function. Here we will introduce a dhcp relay configuration example to help you understand the content and deepen your impression. Let's take a look at these details.

DHCP service settings are used in many local networks. Here we will mainly introduce how to configure the DHCP service on the Server of Windows 2000 Server. We have selected the two most common Server operating systems Windows 2000 Server and Linux as the example to explain, in addition, we will introduce how to configure DHCP on common network devices.
Windows 2
In DHCP settings, we usually work with routers. Here we will introduce the debugging and settings of Cisco routers and DHCP. A company uses Cisco 3620 as the ios dhcp Server. the IP address of the fastethernet0 port connected to the Intranet is 192.168.1.4. The L2 Switch uses two Cisco 2950 and the L3 switch uses a Cisco 3550.
There are two VLANs in the network.
DHCP protocol is widely used, which is especially important for LAN. Here we will explain the management content. For many servers, the related knowledge also needs to be mastered by administrators. So here we will explain the DHCP from the basic aspect.

Configure DHCP NAP enforcementDHCP NAP enforcement allows only compliant computers to receive IP addresses that are granted full network access, while noncompliant computers are assigned a subnet mask of 255.255.255.255 with no gateway IP addresses, restricting full access to the network.I. Installation of NAP1. In Server Manager, click Manage, select Add roles and features, in the wizard window that opens, go to the next step, and in the Select Serve
DHCP Configuration: automatically obtain IP addresses for linux and windows I. Prepare for the experiment 1. Check whether dhcp is installed [root @ vm2 root] # rpm-qa | grep dhcp [root @ vm2 root] # // [root @ vm2 root] # cd/home [root @ vm2 root] # ls // upload dhcp to the home Directory
Application examples
My school is a student apartment, PC owns about 1000 units. Using DHCP assigned IP address, with 4 C class addresses, the actual number of addresses available is about 1000. Because of the frequent presence of private DHCP servers in the building, a large number of hosts cannot be assigned to legitimate IP addresses, and because a significant number of hosts specify IP addresses, confli
We described how DHCP works in the last issue, and then we explained how to configure the DHCP service on the server, and we selected two of the most common server operating systems Windows2000server and Linux as examples, In addition, we will describe how to configure DHCP on common network devices.

Dynamic Host Configuration Protocol (DHCP) is a network protocol used to automatically allocate TCP/IP information to the client machine. Each DHCP Client is connected to the DHCP server in the central position. The server returns the network configuration of the client that includes the IP address, gateway, and DNS server information.
