Question

What are the three ways a DHCP server can allocate IP's?

Answer 1

A DHCP server can allocate IP addresses using automatic allocation, dynamic allocation, or static allocation.

Step-by-step explanation:

A Dynamic Host Configuration Protocol (DHCP) server can allocate IP addresses to devices using three different methods:

1. Automatic Allocation: In this method, the DHCP server assigns a unique IP address to each device on the network without any input from the user. The server keeps track of the IP addresses it has assigned to avoid conflicts.
2. Dynamic Allocation: Here, the DHCP server maintains a pool of available IP addresses. When a device requests an IP address, the server dynamically assigns an available address from the pool. This address may change if the device disconnects and reconnects to the network.
3. Static Allocation: With static allocation, the DHCP server reserves specific IP addresses for specific devices based on their unique MAC addresses. These reserved addresses are always assigned to the respective devices, ensuring consistency.
