wireshark IP

Worked with Bryan Pellitier

1.  216.92.151.75


2. the overall header of the value is ICMP

3.there are 56 toal bytes, 20 of which the bytes go to the IP header, and the other 36 are from the IP datagram.

4. the data can not be fragmented because the fragment line is equal to 0

5.  the amount of Time to live, Identification, and the header always change.

6. constant: header length, version, source IP, desination IP, upper layer protocol, services
has to change: identification, header checksum, time to live.

7. The IP header fields change incremently with each change in field.

8. Identification: 60500
Time to live: 254

9. The identification field will change for all of the ICMP time to live requests, but they will not change with a hop router because they are using the same router.


10. Yes more than one IP datagram was used.

11. The fragment offset is = 0, and therefore this is the first fragment. The length of this is 1500 bytes.

12. It cant be the first fragment, because the offset is not 0.

13. The changes are offset, checksum, flags, total length.

14. 3 packets are created.

15. The fragment offset and checksum will change.
