2.2. How Does DHCP Server Software Work?

DHCP server software works through a series of interactions between the server and client devices, typically following these steps:

1. DHCP Discover: When a client device joins the network, it sends a DHCP Discover message to find available DHCP servers.
2. DHCP Offer: DHCP servers that receive the Discover message respond with a DHCP Offer, proposing an IP address and other network configuration parameters.
3. DHCP Request: The client selects one of the offered configurations and sends a DHCP Request to the chosen server, accepting the offered IP address.
4. DHCP Acknowledgment: The DHCP server confirms the assignment by sending a DHCP Acknowledgment, which includes the IP address, subnet mask, default gateway, DNS server addresses, and lease duration.
5. Lease Renewal: Before the lease expires, the client attempts to renew the IP address by sending a DHCP Request to the server. If the server is available, it extends the lease; otherwise, the client must obtain a new IP address.

This process ensures that each device on the network receives a unique IP address and the necessary configuration information to communicate effectively.

2.3. What are the Key Features to Look for in DHCP Server Software?

DHCP scopes and reservations are essential components of DHCP server configuration. A scope defines a range of IP addresses that the DHCP server can assign to clients. When configuring a scope, you specify the start and end IP addresses, subnet mask, lease duration, and other options that will be provided to clients.

A reservation, on the other hand, allows you to assign a specific IP address to a particular device based on its MAC address. This ensures that the device always receives the same IP address, which is useful for devices that require a static IP address but can still benefit from DHCP management.

2.5. What is the Importance of Lease Time in DHCP Configuration?

Lease time is the duration for which an IP address is assigned to a client by the DHCP server. The importance of lease time in DHCP configuration includes:

• IP Address Availability: Shorter lease times ensure that IP addresses are returned to the pool more quickly, preventing exhaustion in environments with many transient devices.
• Network Changes: Shorter lease times allow network administrators to implement changes more rapidly, as clients will renew their IP addresses more frequently.
