How to make sure a device gets the same IP address from DHCP every time:

To ensure that a specific device always receives the same IP address from the DHCP server, you can configure a DHCP reservation. This assigns a specific IP address to the device’s unique MAC address. The process of configuring DHCP settings varies depending on the DHCP server software or network device you are using. Here is a general overview of the steps involved:

1. Determine the MAC address: Identify the MAC address of the device for which you want to assign a static IP address. The MAC address is a unique identifier associated with each network interface card (NIC).
2. Access the DHCP server configuration: Log in to the DHCP server or the network device acting as the DHCP server. This could be a router, switch, or dedicated DHCP server software running on a server.
3. Locate the DHCP reservation settings: Navigate to the DHCP reservation or static IP assignment section in the DHCP server configuration. The specific location of these settings depends on the device you are using.
4. Add a new DHCP reservation: In the DHCP reservation settings, create a new entry by specifying the MAC address of the device and the desired IP address you want to assign to it.
5. Configure other parameters: Depending on the DHCP server software, you may have additional options to configure, such as specifying the device’s hostname or other network settings.
6. Save and apply the changes: Once you have entered the necessary information, save the changes and apply the new DHCP reservation settings.

By configuring a DHCP reservation, the device with the specified MAC address will always receive the same IP address whenever it requests one from the DHCP server. This approach ensures consistency and simplifies network administration by eliminating the need to manually assign static IP addresses on the device itself.
