Question

In the TCP/IP protocol suite, which one of the following is NOT part of the IP header?

• A. Destination port number
• B. Fragment offset
• C. Source IP address
• D. destination IP address

Answer 1

The correct option is A Destination port number

Destination Port number is NOT in IP header.
Because that IP header has nothing to do with the port number.
Port numbers are used by the transport layer to ensure process to process delivery.
