Overview
Dynamic Host Configuration Protocol (DHCP) eliminates the need for manual IP configuration. When a device joins a network, it 'asks' for an IP address, and the DHCP server provides one from a pool.
The DORA Process
- Discovery: Client broadcasts to find a DHCP server.
- Offer: Server offers an IP address to the client.
- Request: Client requests the offered IP address.
- Acknowledgement: Server confirms the lease of the IP address.
