      Lesson details

      Learning outcome

      I can explain the importance of internet addresses.

      Key learning points

      1. An IP address is a unique number used to identify a device on a network.
      2. Devices on a network are assigned IP addresses.
      3. Domain name servers match website names to IP addresses.
      4. Computers use addresses to access websites.

      Keywords

      • Internet Protocol (IP) address - an identifier, such as 192.168.4.8, that is assigned to a networked device

      • Domain Name Server (DNS) - a system that matches website names to IP addresses

      • Communication - the exchange of information between devices or people

      Common misconception

      The internet knows website names, not numbers.

      Computers use IP addresses (numbers, and DNS helps match names to those numbers).

      Teacher tip

      Use a classroom analogy, such as matching a person's name to their address, to help pupils understand that DNS converts a URL into an IP address that computers use to locate websites.
