Introduction

DHCP Server

What is a DHCP Server?
A DHCP server automates the assignment of IP Addresses and other IP details. The DHCP server holds a bank of IP Addresses. When a computer requests an IP Address, it will assign the computer one from its bank. The DHCP server ensures that each IP Address in use on the network is unique.

Analogy
Obtaining an IP Address from a DHCP server is similar to renting a hotel room. To rent a room (IP address) you must first decide how long you wish to initially stay for. Once a room has been assigned, you can stay there for the entire period of the lease. If you wish to continue living at the house, you can renew before the contract/lease ends. If the owner of the hotel (DHCP Server) rents the room to another person (computer), then they will provide another room for you. If you decide to leave, before your stay expires.

DHCP Server Details
The DHCP Server settings are as follows:
IP Address Range (Start and End IP Address)
This is the range of IP addresses assigned to the DHCP server to be allocated to devices on your network.

IP Address Leases
Lease duration
The lease duration specifies how long the DHCP lease lasts for before it will be renewed. Can be set to expire after 1 to 365 days.

Maximum Number of Leases
This is the maximum number of IP Addresses that the DHCP server will assign at one time.
