DHCP for Ipv4 
1. Determine how the DHCP process functions. 
When the device connects with the router or switch that has enabled the DHCP protocol, the 
DHCP discover message is floated on the network. Based on this request the DHCP server 
allocates one IP address to the computer who have made the request. This is known as the DHCP 
offer message. The system accepts the message and takes the first message that comes along the 
different messages.  (Cheshire, Aboba & Guttman, 2017) 
2. Understand how an end device obtains an IPv4 address. 
The DHCP server then updates the entire connected devices on the network about the IP address 
and other configuration as needed for your system. The IP address is assigned on a lease that 
means it will expire after sometime and you need to request again the DHCP server to grant you 
the IP.  
3. Understand the DHCP relay process. 
As the device is connected the client DHCP uses the destination IP as 255.255.255.255 for all 
broadcast this means the DHCP client will not be able to request the DHCP server on other 
subnets means you can connect to the router at your home but won’t be able to communicate 
with the outside website. In order to do so the process of DHCP/BootP Relay process act as the 
forwarding agent for the clients. The DHCP relay will forward the packets to the outside network 
on behalf of the DHCP client to other DHCP server. The DHCP relay will append its own IP 
address to the source IP address. The server will respond to the message responded via unicast to 
the DHCP Relay agent. (Cheshire, Aboba & Guttman, 2017) 
4. Be able to troubleshoot the DHCP process. 
The DHCP client then run the test to ensure there is no IP conflict on the network. If there a 
conflict is found on the network then client requests the IP from the DHCP server for 10 times 
more. ("RFC 5227 - IPv4 Address Conflict Detection", 2017)
DHCP for IPv6 
1. Understand the SLAAC process. 
As in the IPv4 there are number of ways in which the address can be assigned to the system 
using DHCP v6 used in IPv6.
