Fields in the Ipv4 header

1. Version

   • Contains a 4-bit binary value set to 0100 that identifies this as an IPv4 packet

2. Differentiated services (DF)

   • 8-bit field used to determine the priority of each packet

3. Header checksum

   • Used to detect corruption in the IPv4 header

4. Time to live (TTL)

   • 8-bit binary value that is used to limit the lifetime of a packet

5. Protocol

   • 8-bit binary value indicates the data payload type that the packet is carrying, which enables the network layer to pass the data to the appropriate upper-layer protocol.

6. Source IPv4 Address

   • 32-bit binary value that represents the source IPv4 address of the packet

7. Destination IPv4 Address

   • 32-bit binary value that represents the destination IPv4 address of the packet.
