1. Overview
The interaction between the DHCP Client and the DHCP Server involves both broadcast packets and unicast packets (used during renewal, we know that the general Server Load balancer equipment implements Load Balancing for unicast packet data, so the pure DHCP Client-> DHCP Server architecture basically cannot
About DHCP principles the DHCP Client initializes TCP/IP for the IP lease request packet sent by the customer, and sends a DHCPDISCOVER broadcast packet to the network through UDP port 67 to request the lease IP address. The Source IP address in the broadcast package is 0.0.0.0, and the target IP address is 255.255.255.255. The package also contains the client's MAC address and computer name. Any

I have reviewed the establishment of DHCP today. It is easier to set up DHCP than I think, but it is estimated that there will be many knowledge points, just like DNS, A series of knowledge points will be pulled out in depth. Now, let's get down to it. Now I am writing my review notes.

DHCP (Dynamic Host Configuration Protocol) is a LAN protocol that uses UDP to work with two main purposes: assigning an IP address to an internal network or network service provider automatically, For users or internal network administrators as a means of central management of all computers, in RFC 2131 is described in detail. DHCP has 3 ports, where UDP67 and UDP68 are normal
In the networking configuration, We need to configure multiple Server protocols. Here we will focus on the DHCP protocol and related content of the DHCP server. For TCP/IP networks, basic network configurations, such as IP addresses, subnet masks, default gateways, and DNS, must be configured for each workstation to be interconnected with other computers. For a small network, it may be acceptable to configu

Master An agreement and have an understanding of its work process. Now let's talk about how DHCP works. An important part of learning about DHCP is understanding the DHCP process. First, DHCP is divided into two parts: one is the server side and the other is the client side. The IP address settings of all clients are c
How DHCP works
DHCP is usually used as a communication protocol in the local area network. It transmits broadcast packets to all hosts in the entire physical network segment through a client. If a DHCP server exists in the local area network, in response to the client's IP parameter requirements. Therefore, the DHCP se
We know that DHCP is an IP address management protocol. DHCP is used in many network structures. For example, two computers connected to the Internet must have their own IP addresses for communication. However, due to the limited IP Address Resources, broadband Access operators cannot assign a fixed IP address to each user who installs broadband. The so-called fixed IP address is that even if you do not acc
DHCP
DHCP is the abbreviation of Dynamic Host Configuration Protocol (Dynamic Host Allocation Protocol). Its predecessor is BOOTP. BOOTP was originally used on a network without a disk host connection: the network host uses boot Rom instead of the disk to start and connect to the network. BOOTP can automatically set the TCP/IP environment for those hosts. However, BOOTP has one disadvantage: You mu
