Record Route option stores what type of data in the IP header?

• A. Time stamps
• B. IP addresses of routers along the path
• C. MTU values
• D. Sequence numbers

Answer: (B)

The Record Route option records the path a packet takes by storing the IP addresses of the routers along its route in the IP header. As the packet moves through the network, each router that supports this option appends its address to the field, creating a trace of the path taken. This is different from the Timestamp option, which would record time values at each hop; MTU values relate to path MTU discovery and aren’t stored here; and sequence numbers pertain to transport-layer sequencing, not IP routing records.
