In everyone's impression, the IP address obtained by DHCP has a lease. Once the lease arrives, the client will obtain the IP address again, at this time, the obtained IP address may change compared with the original one, which is unfavorable to network management. If a static IP address is used, the address will not change if the IP address is not moved. However, it is troublesome to change the IP address of each server, which is prone to errors.
In fact, DHCP generally provides the address retention function, which allows the client to allocate a fixed IP address. When DHCP is used in the network, this can greatly facilitate Intranet management. However, it is a little troublesome to keep the Address Configuration. It is a little complicated to say that there are too many configurations. In this case, let's handle the trouble. Haha
The environment described in this article is Windows Server 2003 R2, which is also applicable to Server 2008/2012
1. Calculate the IP addresses and MAC addresses of all clients on the Intranet.

2. collect statistics on the name of each client user, MAC address, IP address to be allocated, and the name of the computer user to create a batch file. The following batch processing is used as an example. 192.168.1.249 is the DHCP server, 192.168.1.0 is the scope, 192.168.1.12 is the address, 00e06602f54c is the MAC address, PC012 is the name, and the computer user is later. This command is to assign 192.168.1.12 to the machine of 00e06602f54c.

The batch processing command is implemented through the Netsh DHCP server scope add reservedip command
The command explanation is taken from the official Microsoft website.
========================================================== ========================================================== ===
Add reservedip
Retain an IP address for the Media Access Control (MAC) address specified in the current scope.
Syntax
Add reservedipReservedIPMACAddress [ClientName] [ClientComment] [{DHCP | BOOTP | BOTH}]
Parameters
ReservedIP
Required. The IP address to be retained.
MACAddress
Required. Specify the physical hardware or MAC address associated with the reserved IP address.
ClientName
Specifies the name of the client to be associated with the remaining client items. If this parameter is not specified, no client name is associated with the reserved client name.
ClientComment
Specifies the client comments associated with the client items to be retained. If this parameter is not specified, no client comments are associated with the reserved client.
{DHCP | BOOTP | BOTH}
Specifies the client type to be associated with the reserved client items. The default value is DHCP.
========================================================== ========================================================== ====
3. Create a scope on the server, and then run the batch processing. Just wait for a cup of coffee to finish.
