DHCP is good if you've got a network that changes constantly. If you owned a hotel that offered free in-room high-speed internet over Ethernet, DHCP would make your life much simpler: instead of issuing a static IP address to every guest, you'd just tell them to set their laptops to use DHCP and plug into the jack in the wall. If you're running a network that doesn't change much over time, you can still use DHCP but I think it's kinda silly--it's as easy to plug in an IP address and subnet mask as it is to use DHCP.
DHCP should only be enabled if your network is set up for dynamic IP addressing.
Router is usually configured as a DHCP client for WAN (Internet) network and as a DHCP server for local network.
According to Microsoft:How to use automatic TCP/IP addressing without a DHCP server"A Windows-based computer that is configured to use DHCP can automatically assign itself an Internet Protocol (IP) address if a DHCP server is not available. For example, this could occur on a network without a DHCP server, or on a network if a DHCP server is temporarily down for maintenance."For more information, see Related Links, below.
Dynamic Host Configuration Protocol (DHCP) is a network management protocol used in IP networks, including those connected to Windows 2000 operating systems. It automates the process of assigning IP addresses, subnet masks, default gateways, and other network configuration parameters to devices on a network, allowing them to communicate effectively. By using DHCP, network administrators can manage address allocation dynamically, reducing the chances of IP conflicts and simplifying the administration of IP address assignments. Windows 2000 includes built-in DHCP server and client functionality, making it easier to deploy and manage network configurations.

The service that automates the assignment of IP addresses, subnet masks, gateways, and other IP networking parameters is called Dynamic Host Configuration Protocol (DHCP). DHCP allows network devices to obtain necessary network configuration settings automatically, reducing the need for manual configuration. By using DHCP, administrators can efficiently manage IP address allocation within a network, ensuring that devices can connect seamlessly.
DHCP Server (Dynamic Host Configuration Protocol)
The device is looking for a DHCP server to obtain a DHCP address.
