Taking the two subnets A and B managed as an example, subnet A is configured with a dhcp server, and subnet B does not have a dhcp

Mask: Speaking of masks, you have to talk about the division of subnets and subnets, now the IP using CIDR to divide the subnet, IP address and subnet mask bitwise phase, the results can be represented by the Division and definition of subnets.3.

This article mainly introduces how to use a vrodhcp to build DHCP. After reading the specific operation steps, I believe you will understand it.
There are many ways to use a DHCP server. Here I will introduce how to use a vro as a DHCP server.

DHCP servers are often seen in many enterprise-level network structures. The company has recently expanded its office business and established subsidiaries in many regions. As the subsidiary has just been established, it does not have enough funds to purchase servers, and the IP addresses of office machines are to be managed by means of automatic DHCP allocation, without a dedicated

In many cases, we need to build DHCP servers through vswitches and routers. So how can we use routers to build DHCP servers? This article describes the process in detail.
Project requirements: XX enterprise has three departments, which are divided into VLAN for the three departments in layer-3 switching.
IP address planning is as follows:

Now we have defined a DHCP user class with the ID of Long. We need to configure this user class below.

division of subnets and subnets. Today's IP uses CIDR to divide subnets, and IP addresses and subnet masks are bitwise AND. Results can be used to represent the division and definition of subnets.3.

Dynamic Host Control Protocol (DHCP) provides a convenient way for network administrators to provide network layer addresses for changing network hosts or dynamic networks, the most commonly used DHCP service tool being iscdhcpserver. The purpose of the DHCP service is to provide the host with the necessary network information to communicate with other hosts conn

Experimental background:
In the enterprise network environment in the absence of DHCP server configuration, often encountered such a situation, users do not know how to configure IP address; IP addresses often conflict; an administrator can frequently make an error in a single configuration of an IP address; customers of laptops often move from one subnet to another. There is a need to manually replace the
