Think of an office setting. Call center, business office, somewhere you can connect to the internet and do computer work. When you connect to the network, you need an IP address to navigate the internet. DHCP allocates IP addresses to devices on a network. It is one of the most commonly used IP services.

Key Takeaways:

• DHCP is a client-server protocol*.
• A DHCP server maintains a pool of available IP addresses and assigns one of them to the client.
• A client is a device that request network parameters like an IP address.
• Cisco routers can be configured as both DHCP client and DHCP server.

*A client-server protocol is a relationship between a one program (a client) that will request information from another program (a server).
