Describe the major structure of an IP packet and explain the main functions of the IP headers.
a. An IP packet consists of an IP header and an IP payload. The IP payload may be an entire TCP packet passing down from the TCP layer, or a fragmented TCP packet (when the TCP packet is too long to be enclosed in one IP packet). The IP header is responsible for forwarding the IP packet to the next router, eventually to the destination computer.
b. An IPv4 packet contains a 32-bit source IP address of the sending computer and a 32-bit destination IP address of the computer the data is meant to send to.
c. All of the above
d. None of the above
