1) Here, the headers are as follows:
Ethernet Frame 629
Ethernet II Header
IP Header
Transport Header(Transmission control protocol)
HTTP header.
2) Ethernet II Header - Second layer of OSI Model
i) It tells about the source physical address(MAC address), which in this case is: (00:50:56:01:19:fd)
ii) It tells about the destination physical address(MAC address), which in this case is: (00:50:56:01:27:d5)
IP Header - Internet Protocol Header(Network layer or Layer 3)
i) Source IP, which in this case is: 172.31.2.196
ii) Destination IP, which in this case is: 72.21.91.29
TCP Header - Transport Layer(Layer 4)
i) Source Port No., which is 50840 here .
ii) Destination Port, which is 80 here.
Ports are required to create sockets and initiate sessions for the reliable communication.
