Description
DHCP is used to dynamically assign IP addresses to hosts through a network. It is a flexible feature, allowing you to simulate static configuration through permanent assignments, or to give a certain IP specifically to a certain host.The practical examples show how to configure the DHCP tools and how they can be used to assign a dynamic IP address to a device.

Objectives
The trainees will learn the particularities of DHCP: what members are involved, how each participant works, what messages are exchanged and what tools can be used to provide the service.
After the course they will be able to understand the principles of the protocol, test on their own how it works, debug possible issues and configure networks to use it.

Target Audience
- Developers and testers that need DHCP
- System engineers
- Network administrators
Prerequisites
Basic notions of routing and IPv6 particularities.
Roadmap
- General information
- DHCP mechanisms overview: learn how a server can assign addresses in its own subnet, but also in a different subnet through a relay
- Types of allocation: dynamic, manual or automatic
- IPv4
- Packet format and DHCP options: almost 100 options can be set for DHCP creating a high grade of flexibility; learn which options are mandatory and in what situations
- Compatibility with BOOTP: see how DHCP works with its ancestor BOOTP, without causing interruptions or misconfiguration
- Packet types and exchange mechanisms: learn the basic mechanisms that DHCP uses to assign an IP to a client
- Client State Machine: the client is working based on a state machine; learn what information goes in the message for each state
- Server Processing: the server must decide which packets to process and which to reject; see how you can configure it for a robust network
- Captures of packets: see how the actual DHCP packets look like
- Agent Relay behaviour and options: what can be done when we have more subnets and only one server? Check out what an Agent Relay can do
- Tools that implement DHCP: details about ISC DHCP server, client and relay applications
- Security aspects: DHCP is very useful and time-saving but it also can be easily attacked; see what can be done to keep out threats
- Practical example: see the theory put in practice with the tools mentioned in this presentation
- IPv6
- IPv6 overview: what is changed in IPv6 logic that impacts DHCP
- Format and Types of messages: the packet is better organised than in IPv4 but see how the needed information is found in this new format
- IPv6 specific identifiers: since IPv6 permits more IPs for the same host, new identifiers are needed to organise them
- Types of Message Exchange: more types of packets, less confusion
- Client logic: the same state machine as in IPv4 is used but the information put in the message is differently organised to make things simpler
- Server behaviour: learn how the server meets the new challenges that come with IPv6
- Agent Relay description: the agent does the same job as in IPv4 but it does it differently
- Security aspects: DHCP for IPv6 is more secure than for IPv4; several attacks can be prevented by configuring the members with security options
- Practical example: see the theory put in practice
