Which OSI layer header contains the address of a destination host that is on another network?

  • A. application
  • B. session
  • C. transport
  • D. network
  • E. data link
  • F. physical
Answer: Option D.

Only network address contains this information. To transmit the packets the sender uses network address and datalink address. But the layer 2 address represents just the address of the next hop device on the way to the sender. It is changed on each hop. Network address remains the same.
