Which IPv6 header field is equivalent to the TTL?
- A.
Hop Limit
- B.
Flow Label
- C.
TTD
- D.
Hop Count
- E.
Scan Timer
Correct Answer
A. Hop LimitExplanation
The correct answer is "Hop Limit". In IPv6, the Hop Limit field serves the same purpose as the TTL (Time to Live) field in IPv4. It is an 8-bit field that limits the number of hops or routers that a packet can traverse before being discarded. Each router that processes the packet decrements the Hop Limit value by 1. When the Hop Limit reaches zero, the packet is discarded. This mechanism helps to prevent packets from endlessly circulating in the network and ensures efficient routing.Rate this question:
