Now let us dive deeper into the elements that constitute an IP address:

  1. Network Prefix:

    • This part indicates the network or subnet to which the device belongs.
    • It allows routers to distinguish between different networks when forwarding data packets.
    • For instance, in our earlier example, 192.168 would represent the network prefix.
  2. Subnet Mask:

    • The subnet mask determines which portion of the IP address represents the network and which part identifies hosts on that network.
    • It enables devices to determine whether another device is located on their local network or requires routing through other networks.
    • Using our previous example, if the subnet mask was, it means that only the first two parts (192.168) belong to the network.
  3. Host Identifier:

    • This component specifies a unique identifier for each individual device within a particular network.
    • It helps differentiate one device from others sharing the same network prefix.
    • Continuing with our example, 0 and 1 would serve as host identifiers for two respective devices.
  4. Broadcast Address:

    • The broadcast address is a special IP address used to send data packets to all devices on a given network.
    • When a packet with the broadcast address is sent, it will be received by every device within that network.
    • In our case, would represent the broadcast address for the hypothetical network.

Understanding the structure of an IP address allows us to comprehend how networks are organized and how information travels between devices. Next, we will explore different types of IP addresses, which play distinct roles in networking environments.
