Summary of precautions for installing DHCP servers

Next we will introduce the precautions for installing the DHCP server. Before installation, we must have some knowledge about this, so we also want to avoid some possible errors during the installation process. So next. Let's take a closer look at the specific content.

Considerations for installing DHCP servers:

The DHCP server must use a fixed IP address.

Plan available IP addresses of DHCP servers

The following describes how to plan a DHCP address pool. The following three problems need to be considered when planning a DHCP server:

Considerations for installing DHCP servers 1. How many DHCP servers need to be created

Generally, every 10000 customers need two DHCP servers, one as the master server and the other as the backup server. However, in actual work, you must consider the router's location in the network, whether a DHCP server is established in each subnet, and the transmission speed between network segments. If the two CIDR blocks are connected by a slow dialing, you need to set up a DHCP server in each CIDR block.

There is no limit on the number of customers for a DHCP server. In practice, the IP address category of the IP address used by the user and the server configuration, such as disk capacity and CPU processing speed) limits

Considerations for installing DHCP servers 2. How to support other subnets

If the DHCP server is required to support other subnets in the network, first determine whether the CIDR blocks are connected by routers and whether the routers support DHCP/BOOTP relay agent. If the vrodhcp does not support relay agent, use the following solution to solve the problem:

§ A Windows 2000 Server or Windows NT Server 4.0 Computer installed and set it to use the DHCP Relay Agent component

§ A computer with Windows 2000 Server installed and set as a local DHCP Server

Considerations for installing DHCP servers 3. Problems to be considered during Enterprise Network Planning

§ The DHCP server is located in the network and minimizes the broadcast through the vro

§ Specify the option type for the DHCP Client in each range and set the corresponding value

Fully aware of the impact of slow WAN connections.
