Explanation / Answer

Question a

Several Email (SNMP) header fields which would be important to Network Forensic Analysis are as follows:-
a.Message-ID : It contains a unique string for the mail which is sent.
b.From : It contains the name and email of the sender
c.Reply-To : It contains the details about the receipents of the mail.
d.List-ID : Universal mailing identification string which is unique in nature.

Question b

For tracking and email we have to read about different message header.The email contains an header name Received.It is of the following syntax
Received:<User private IP><send to><public ip>
From here we can get the private IP of the computer from which it is sent.And the respective From header contains the sender details.

Question c

In IPv6 the packaet processing is much more effective.The main part is that IPv6 doesn't contain any ckecksum which saves the time of calculating the checksom after every router hop.Hence this provides a better end to end connectivity.

Question d

In IPv6 the routing table size is very less which in turns provides faster forwarding and routing.

Question e

IPv6 provides one big advantage and that is the address auto configuration.So the host will generate the IP automatically by adding the MAC address which is converted in 64 bits of the local link prefix.Hence by this way IPv6 provides the stateless configuration.

Question f

The authenticity,data integrity is the key feature of the IPv6.In this respect it provides better security than the others.
