Problem: In discussing AH processing, it was mentioned that not all of the fields in an IP header are included in MAC calculation.
- For each of the fields in the IPv4 header, indicate whether the field is immutable, mutable but predictable, or mutable (zeroed prior to ICV calculation).
- Do the same for the IPv6 header.
- Do the same for the IPv6 extension headers.
In each case, justify your decision for each field explain clearly your work.
