Automatically assigning workstation addresses using a DHCP server

In a large network, you need to assign various addresses (IP address, subnet mask, gateway, DNS address, WINS server address, and so on) and their associated parameters to each workstation. This work is very heavy and prone to mistakes. You can use a DHCP server to automatically assign workstations to your network.

Overview of DHCP servers

DHCP (Dynamic Host Configure Protocol) is a ICP/IP standard protocol that simplifies host IP address assignment management. A network administrator can use a DHCP server to dynamically assign IP addresses to clients and other related environment configuration work.

The advantages of 1.DHCP service

Each computer on a TCP/IP network must have a unique IP address. The IP address (and its associated subnet mask) identifies the host and the subnet it is connected to. If you move your computer to a different subnet, you must change the IP address. DHCP allows users to dynamically assign IP addresses to clients through the IP address database of a DHCP server on the local network.

As an excellent IP address management tool, DHCP has the following advantages:

(1) Improve efficiency. The computer will automatically obtain IP address information and complete configuration, instead of manual configuration of the heavy work, and reduce the manual configuration may occur errors, greatly improve the efficiency.

(2) easy to manage. When the IP address segment used by the network changes, you can simply modify the DHCP server's IP address pool without having to modify all the computer addresses in the network on a per-table basis.

(3) Conserve IP address resources. In a DHCP system, the DHCP server raises the IP address only when the DHCP client requests it, and the address is automatically released when the computer shuts down. Typically, computers in the network do not all turn on at the same time, so fewer IP addresses can meet the needs of more computers.

2. Scope

The scope is the complete contact range of IP addresses available on the network, also known as IP address segments or IP address ranges. DHCP provides IP address assignment services to clients in the scope for basic administrative units. Scope is also called domain, is the network can manage IP address grouping, manage the client IP address to read through any related configuration parameters distribution and assignment.

3. Super Scope

A superscope is a collection of scopes that are managed as a single entity, that is, when there are multiple scopes on the DHCP server, you can compose a superscope. A superscope is used to implement the inclusion of multiple logical IP subnets on the same physical subnet. Contains only the list of member scopes or scopes that can be activated at the same time in the superscope. But the superscope is different from setting the specific scope. If you want to configure most of the properties used within a superscope, users need to configure the member scope or child scope properties individually.
