What are the four functions of dhcp?

The four primary functions of DHCP (Dynamic Host Configuration Protocol) are:

1. IP Address Allocation: DHCP automatically assigns IP addresses to devices on a network, ensuring that each device has a unique address.
2. Configuration Information: It provides essential network configuration parameters, such as subnet mask, default gateway, and DNS server addresses.
3. Lease Management: DHCP manages the lease of IP addresses, allowing addresses to be reused and ensuring efficient use of the available IP address space.
4. Dynamic Updates: It enables devices to request new IP addresses as needed, facilitating easy network changes and mobility for devices.
