DHCP fixed IP Address

Using a fixed IP address of the DHCP service involves many IP addresses. We need to know That DHCP management is also for IP addresses. Here we will focus on the problems related to the use of the DHCP service fixed IP address.

DHCP service fixed IP Address: how to assign a fixed IP Address

In the Windows 2000 Server network operating system, DHCP (Dynamic Host Configuration Protocol) is provided. It is with DHCP that the above problems can be solved.

DHCP works like this: when a computer set to automatically obtain an IP address logs on to the network, it will send a "rent" request to the network for an IP address, the DHCP server responsible for providing the IP address responds to this request and provides the computer with an idle IP address. Since it is a "lease", of course there is a "lease period ". However, as long as the "lease period" is set to "permanent", each DHCP client will occupy this IP address forever.

The procedure is as follows: Open the DHCP manager in Windows 2000 Server, right-click the Server name, and click "create scope" in the pop-up menu ", the scope is the IP address range allocated to the client by DHCP.

The "name" of the scope is only used to prompt users. You can enter any content. However, you must plan the IP address range according to the size of the network classroom. In this example, it is set to "192.168.0.11 ~ 192.168.0.60 (50 student machines), enter "192.168.0.11" in the "Start IP Address" field, and "end IP Address" enter "192.168.0.60 ", the default "subnet mask" is "255.255.255.0 ".

DHCP service fixed IP Address: Set the IP address range

Sometimes, you want to leave a portion of the IP address segment dedicated. If you want to assign it to the server, you need to "exclude" the IP address range. Enter a single IP address or IP address range to be retained, and click [add]. Otherwise, click [next]. The default "Lease Term" of DHCP is 8 days. In the IP address column of the above service, enter and "add" the IP address of the server, and then select "yes, I want to activate the scope" as prompted ", click [finish] to complete DHCP settings.

Why? Isn't the IP address always assigned? So how can we change the lease term to permanent? Do not worry. In the DHCP window, right-click "Scope" and click "properties" in the pop-up menu. The "general" setting window for "Scope attributes" appears, change the lease period of the DHCP client to "unlimited", so that there is no deadline limit.
