Which three IPv4 header fields have no equivalent in an IPv6 header? (Choose three.)
- fragment offset
- flag
- identification
- version
- protocol
- TTL
Explanation & Hint: Unlike IPv4, IPv6 routers do not perform fragmentation. Therefore, all three fields supporting fragmentation in the IPv4 header are removed and have no equivalent in the IPv6 header. These three fields are fragment offset, flag, and identification. IPv6 does support host packet fragmentation through the use of extension headers, which are not part of the IPv6 header. |
