dhcp stands for

DHCP is the acronym for Dynamic Host Configuration Protocol, which is formerly a BOOTP. BOOTP was originally used for diskless host-connected networks: Network hosts use the BOOT ROM instead of disk to start and connect to the Internet, BOOTP can automatically set the TCP/IP environment for those hosts. But BOOTP has a disadvantage: you need to obtain prior to the client's hard address, and the corresponding IP is static. In other words, BOOTP is very

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

1) The host sends a DHCP Discover broadcast packet looking for a DHCP server on the network; unicast packets, addresses,2) The DHCP server sends DHCP offer unicast packets to the host, including IP address, MAC domain name information, and address lease, address, domain name information, and the lease period;3) The hos

We all know that each computer needs an address to access the Internet normally. This address is what we often call an IP address. How can we effectively manage these IP addresses as network administrators? You can set the corresponding IP address, subnet mask, gateway address, DNS address, and other network parameters for each computer, but it is very cumbersome and heavy workload, conflicts often occur in practical applications. How can we effectively allocate these network parameters? The

We have explained a lot about the DHCP protocol, and you may feel confused about this part. It doesn't matter. Let's take a look at the definition of this agreement. We can look back and see that there may be unexpected gains. DHCP protocol Introduction DHCP, full name: Dynamic Host Configuration Protocol, Chinese name: Dynamic Host Configuration Protocol, its pr

In the course of learning the DHCP protocol, we may find many important points, especially the use of DHCP servers. Here we will mainly introduce how the DHCP server automatically assigns IP addresses to the DHCP Client and how the DHCP Service implements

We have learned a lot about the content of DHCP. We have already understood the definition and structure of DHCP protocol. Here we will analyze and explain the content of the DHCP work process. Brief description of DHCP process: DHCP-Client-A

Previously, we resolved the DHCP service content. Here we will mainly introduce the content of the DHCP server. Let's take a closer look at the application environment and Message format of the DHCP server. Hope to help you. DHCP server Application Environment of the DHCP se

We have also introduced two DHCP relay faults before. I don't know if you still remember them. If you are not clear about it, You can briefly review it. The DHCP relay fault described here is about the problem that clients of different business types cannot obtain IP addresses of different network segments through relay. DHCP relay failure ◆ Network Environment S

Xiao Zhang is one of the company's local subnet Saes.grfwgz.com, because all are marketing department employees, although there are many employees, but in general, only a small number of employees in the unit use the network, so in order to save IP address resources, IP address using DHCP automatic distribution, the network segment for 192.168.0.1 29~192.168.0.158. The following are the specific configuration methods. 　　 Because the

The DHCP lease is divided into the following six processes:1.Client request IP Address:The client sends a DHCP Discover packet in broadcast mode to find the DHCP server. The broadcast contains the MAC and computer names of the DHCP client.2.Server Response:When the DHCP serv

For DHCP servers, we can set multiple hosts. So how can I use a multi-host DHCP server to connect to multiple independent subnets? Next we will mainly explain this problem. 1) use a multi-host DHCP server to connect to multiple independent subnets. /NIC1: 192.168.1.1 --- vswitch group 1 --- subnet 1 DHCP server/ \ NIC2

1. DHCP spoofing attacks 1. a DHCP attacker can also provide SERVER services in a VLAN. 2. DHCP attackers will respond to the DHCP Client's sending request information. 3. attackers will allocate IP addresses and other information and default gateways to DHCP clients. Note:

http://debugo.com/dnsmasq/ DNSMASQ is a compact and convenient tool for configuring DNS and DHCP for use in small networks. It provides DNS functionality and optional DHCP capabilities to replace services such as DHCPD (DHCPD service configuration) and bind, which are simpler to configure and more suitable for deployment of virtualization and large data environments.DHCP service Some of these key configura

DHCP (Dynamic Host Configure Protocol) It is a Dynamic Host Configuration Protocol widely used in TCP/IP networks. Using dhcp protocol, it has many simple and easy-to-use advantages, mainly manifested in: the network administrator can verify the IP address and other configuration parameters without checking each host. DHCP does not lease the same IP address to bo

Upgrade of the DHCP server for Windows server 2003-2012Several previous articles introduced the construction of DHCP server, backup and restore, and the migration of DHCP server. So today I would like to introduce you or the relevant content, and will use the service backup and migration operations to implement the DHCP
