In this presentation on DHCP explained, the information regarding the DHCP protocol is provided in a systematic order, beginning with what is dynamic host configuration protocol. Continuing with the DHCP server configuration and the allocation method in DHCP protocol, moving along with understanding some of the DHCP settings including lease, scope and address reservation for an IP address and also understanding the operation model of the DHCP protocol according to which the client receives its IP address and network configuration settings needed to access the internet. The topics covered in this video of DHCP Explained presentation are: 1. What Is DHCP? 2. DHCP Allocation Methods 3. DHCP Settings 4. Operation Model The DHCP(Dynamic Host Configuration Protocol) protocol is a network protocol, which is designed to assign an IP address to the device, which works on the client-server architecture and is based on the dynamic allocation method. The protocol works on the operation model constituting four DHCP services, according to which the server allocates an IP address to the system. What Is Cyber Security? Cyber Security involves techniques that help in securing various digital components, networks, data, and computer systems, from unauthorized digital access. There are several ways to implement cybersecurity, depending on the kind of network you are connected to and the type of cyberattacks you are prone to. A few ways to implement cybersecurity are defining clear boundaries, using network security control devices like Firewalls and IDS.

5. What Is DHCP?
DHCP(Dynamic Host Configuration Protocol) is a network protocol, which
assigns IP addresses and configures network settings for devices to access
internet services using the client-server architecture.
DHCP Server
Access Internet
10.0.0.4
IP
10.0.0.5
IP

6. Allocation Methods

7. DHCP Allocation Methods
Manual Allocation,
also known as Static
IP.
Dynamic Allocation,
uses client-server
architecture.
TYPES

8. Manual Allocation
 In this allocation process, the device is
assigned the IP address by the user
manually.
 This is done by operating the system’s
network configuration settings.

9. Dynamic Allocation
 In this process, the DHCP server
reserves an IP address for the client
system and assigns dynamically.
 The assigned IP address is given on
lease which is temporarily assigned.
Server
10.0.0.5

LEASE
10.0.0.5
IP Address
 The IP address assigned is
temporarily provided and
gets expired after that.
 The lease structure is
designed to so that the
server has few IP address in
the scope.

14. Operation Model

15. Operation Model
The DHCP client sends the message,
DHCPDISCOVER
port:68, port:67
src IP:0.0.0.0 dst:255.255.255.255
DHCP Client
DHCP Server
How Do I connect to
the internet?

16. Operation Model
Then DHCP server reserves an IP address,
DHCPOFFER
src IP:10.10.0.0 dst:255.255.255.255
DHCP Client
DHCP Server
Reserves an IP address
for the client.

17. Operation Model
Next the client response to the offer,
DHCPREQUEST
src IP:0.0.0.0 dst:255.255.255.255
DHCP Client
DHCP Server
Confirms the reserved
IP address.

18. Operation Model
Then DHCP server sends a DHCP pack,
DHCPACK
src IP:10.10.0.0 dst:255.255.255.255
DHCP Client
DHCP Server
