What is DHCP?
DHCP is an automation protocol used in networks to dynamically assign IP addresses, subnet masks, gateways, and DNS information to connected clients.
How does DHCP work?
When a device connects to a network, it sends a request to a DHCP server. The server responds with an available IP address and related configuration parameters. The assignment is time-limited (a lease), which allows for efficient allocation of addresses.
Functions commonly handled by DHCP:
- Automatic IP address management
- Centralized configuration
- Ability to assign static reservations based on MAC addresses
- Prevention of IP conflicts in larger networks
