Which Protocol Is Used to Automatically Assign IP Addresses to Hosts?

Answer : The Dynamic Host Configuration Protocol (DHCP) is used to automatically assign IP addresses to hosts.

Purpose of DHCP

DHCP is designed to reduce the administrative burden and complexity of manually configuring IP addresses for networked devices.

How DHCP Works

• A device connects to the network and broadcasts a DHCP discovery message.
• A DHCP server receives the discovery message and responds with an offer message that includes an IP address and other network configuration information, such as DNS server addresses and the subnet mask.
• The device accepts the offer, and the server allocates the IP address to the device, usually for a limited lease time.

Benefits of DHCP

• Automates the IP address configuration process, ensuring devices can communicate on the network without manual setup.
• Helps prevent IP address conflicts by managing the pool of addresses.

Conclusion

DHCP plays a critical role in modern networks by dynamically assigning IP addresses to devices, simplifying network management, and ensuring efficient use of IP addresses.
