Network addressing
Lesson details
Learning outcome
I can explain how different types of network addressing are combined to enable devices to communicate on a network.
Key learning points
- IP addresses identify devices on a network.
- DHCP assigns IP addresses automatically.
- DNS converts domain names into IP addresses, which identify devices on the internet.
Keywords
IP address - a unique number assigned to each device on a network, used to identify it and allow it to send or receive data
Domain name server (DNS) - a server that works to resolve domain names to corresponding IP addresses
Common misconception
All devices on a network use the same IP address, so there’s no need for private or public IPs or DNS.
Each device needs a unique private IP address on a local network. To access the internet, the router uses a public IP address. DNS translates website names into IP addresses so devices know where to send data.
Teacher tip
Use the school network as a relatable example. Highlight how each device in the classroom (laptop, printer, tablet) has its own private IP but shares one public IP when browsing online.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
