1. DHCP protocol design goalsThe main goal is to make the management of TCP/IP-based networks easy to implement and maintain. Some goals of Microsoft DHCP are as follows: ◇ Centralized management of TCP/IP subnet. All IP addresses and their configuration parameters are stored in the DHCP server's central database. ◇ Automatic TCP/IP IP Address Allocation and conf

DHCP is the abbreviation of Dynamic Host Configuration Protocol. Its function is to dynamically allocate IP addresses for network connections. It allows the client computer to automatically obtain network settings from the network server. The DHCP server makes it easy for the network administrator to add or delete network nodes in the management network or reconfigure the network, without the need to manual

We know that DHCP is a powerful IP management protocol. Some problems may occur when we set up servers and network applications. This article will answer questions about the same IP address and DHCP address. I hope this article will help you. Q: Why is the same ip address obtained through DHCP? The home computer shares the Internet through the home tplink router.

Many people may not know how to use ADSL Modem to build DHCP servers. In Lan, IP Address Allocation is always a headache for administrators. After setting IP addresses for each client, you can change the IP address when you encounter "Good Guys". Either you cannot access the Internet or some software cannot run properly, causing a lot of unnecessary trouble. If we use the ADSL Modem to share the Internet, there is no need to manually specify the IP ad

schematic 4-step lease process for DHCPThe DHCP lease process is the process by which the DHCP client obtains the IP address dynamically. The DHCP lease process is divided into 4 steps: ① client requests IP (client sends DHCPDISCOVER broadcast packet); ② Server response (server sends DHCPOFFER broadcast packet); ③ client selects IP (client sends DHCPREQUEST broad

The use of DHCP is no stranger. So we usually establish a DHCP server in a network. How should we supervise it? In a network using TCP/IP protocol, each computer must have at least one IP address to communicate with other computers. To facilitate unified planning and management of IP addresses in the network, DHCPDynamic Host Configure Protocol and Dynamic Host Configuration Protocol have emerged. This kind

1.DHCP IntroductionDHCP (Dynamic Host Configuration Protocol) runs in client/server mode, and the DHCP server is responsible for centrally managing IP configuration information (including IP address, subnet mask, default gateway, DNS server address, and so on). DHCP uses UDP as the transport protocol, the server listens on a port number of 67, and the client port

The DHCP protocol is developed by the BOOTP (Bootstrap Protocol) protocol, which is designed to reduce th

The role of the DHCP server:The DHCP server has no doubt that the IP client loses some or all of its ability to access the network without running a DHCP server. It can be said that the DHCP server is one of the powerful assistants of enterprise network administrator. With the DHCP
