IP - Internet Protocol

When transmitting messages, this protocol is responsible for providing the destination address and to recognise incoming data packets.

For sending data the IP rules (protocol) include

  • Add the destination address to each data packet
  • Add it own address to indicate where it came from

For receiving data packets the IP rules (protocol) include

  • Accept data packets that have its own address attached
  • Ignore all data packets that do not contain its own address

This TCP/IP process is shown in the diagram below.
