First you need a DHCP server that distributes IP addresses. This machine will serve as the base for all DHCP requests, so it must have a fixed IP address. In a network, we can therefore have only one machine with a fixed IP address, the DHCP server.
To do this, the technique used is broadcasting: the machine will simply send a special broadcast packet on 255.255.255.255 with other information such as the type of request and the connection ports… on the local network.
This is the subtlety of DHCP: you can optimize the allocation of IP addresses by playing over the term of the leases. The problem is there: if no address is released after a certain time, no more DHCP requests can be satisfied, for lack of addresses to distribute.

This is the subtlety of DHCP: you can optimize the allocation of IP addresses by varying the duration of the leases. The problem is there: if no address is released after a certain time, no more DHCP requests can be satisfied, for lack of addresses to distribute.

DHCP allocates addresses in slices (also called ranges), which are ranges of IP addresses defined when the server is configured. Each served subnet has at least one slice and, if applicable, fixed addresses. A slice is simply characterized by its extreme addresses (192.168.1.30 to 192.168.1.45, for example), called limits.

As the main interest of DHCP is the automatic configuration of a large number of machines, the fixed addresses on the network are treated separately. This is a simple list of addresses that must be excluded from the configured address ranges, starting with that of the DHCP server itself. But the server is not the only one affected by fixed addressing: the address of certain network nodes must be fixed. This is the case for printers, but also for Web or DNS servers. All must be systematically present at the same address in order to be permanently accessible.

Beyond the spatial aspect of the network represented by the slices, DHCP also works according to time. A DHCP server works like a telephone switchboard: when a line is released, it must be made available, the same goes for an IP address. On each DHCP server, the period of validity (or lease) of the IP addresses is therefore fixed slice by slice. You can configure the renewal request dates, generally sent at half, three quarters and seven eighths of the lease. If the request proves unsuccessful, another parameter indicates the time during which the machine concerned will be able to broadcast requests to find another DHCP server.

Error DHCP server not responding Ctrl1ws

When requesting an IP address, all the machines
are queried to see who is the DHCP server,
and all servers respond. After accepting the
future client, the first DHCP server to respond
notifies the client of the required information.

Each served subnet has at least one slice and, if applicable, fixed addresses. A slice is simply characterized by its extreme addresses (192.168.1.30 to 192.168.1.45, for example), called terminals.

Do I need to install a DHCP server?

The choice is up to the administrator. The following considerations should be taken into account:
Advantages
This dynamic addressing reduces maintenance problems on a medium-sized network: any new machine can be integrated into it quickly. In addition, it is possible to communicate other dynamic network configuration information via DHCP mode, such as the address of the external DNS server, for example. The network configuration of the clients is thus updated with each new connection to the server. This simplifies the configuration of client network properties.
List of possible options transmitted via DHCP mode:
IP address
Subnet mask
Default gateway IP
DNS server IP
WINS Server IP
Cons
Degraded performance on initial connection. You also need to configure the DHCP server.
Note that one DHCP server is required per subnet.

Control panel: “Network” icon. Services…
Button <Add…> . Choose “Microsoft DHCP Server” from the list of services. Validate…
Configuration of the TCP/IP protocol of the server cards (in “Network properties…”) Internal card
Private static IP IP address
ex: 172.16.1.1
Gateway None (for the moment, the proxy service is not yet installed)

Starting the DHCP service
In the server manager: select the server.

Configuring the DHCP service

“Start\Administrative Tools (Common)\DHCP Manager” menu.

Select “Local machine” (because it is a local DHCP server). Note also that it is not possible to specify a “gateway” option for a global scope.
“Scope\Create…” menu
NB: if the menu is grayed out, double-click on the “Local machine” icon. The above menu becomes available.
Complete the following fields (mutatis mutandis) in the IP address pool:
NB: the “Name” and “Comment” fields are optional.
Start of scope 172.16.1.1
End of scope 172.16.1.254
Mask 255.255.255.0
Unlimited lease

Note: you need to exclude from the scope the addresses that you want to assign in static mode to particular workstations:

Static ranges must be provided for:

the server(s) (s): 172.16.1.1 to 172.16.1.10
print boxes (HP-JetDirect type): 172.16.1.240 to 172.16.1.253
the router (if you are not using a proxy server ): 172.16.1.254 to 172.16.1.254
Suppose we need a static address for two specific stations, we can also exclude the range 172.16.1.11 to 172.16.2.12 to assign them these two addresses. To make this address reservation, you also need to know the MAC address (Ethernet card identification): this information will be sent to you by the WINIPCFG commands under 95 and IPCONFIG under NT.
To exclude these ranges, complete the fields in the “Exclusion range” as follows:
Start address 172.16.1.1 End 172.16.1.1

Validate by clicking on the [Add] button.

And so on for the other ranges to exclude.

A dialog box asks if you want to enable the scope. Accept. Otherwise, remember to do it manually by expanding the server in the main window: double-clicking on “Local machine” will bring up the light bulb and the scope in square brackets. The “on” bulb means that the service is started.

Select the scope in square brackets.

Drop down the “DHCP Options\Extended…” menu. Activate the “Router” option and possibly other options if you wish.
