THE IPV4 HEADER. Match each of the following fields in the IP header with its description, function or use Vocab list: Header check sum field- Version field- Fragment offset field- payload/data field- Time to live field- Type of service field- Upper layer field- Length Field- Please match it to these one's below, thank you The field contains the internet checksum of this datagram’s header fields. This field contains the IP protocol version number. This field is used for data fragmentation/ reassembly. The field contains the “protocol number” for the transport layer protocol. The value in this field is decremented by each router; when it reaches zero, the packet must be dropped. This field contains ECN and differentiated service bits. This Field contains a UDP or TCP segment for example. This field indicates the total number of bytes in datagram

Captured Data Analysis Count how many TCP packets you received from / sent to your site or YouTube, and how many of each were HTTP packets. Determine if any TCP packets with SYN or PSH flags set were sent from your host or received from yoursite/Youtube Go flag-by-flag and count how many packets have tcp.flags.push set, then how many have tcp.flags.syn set, and finally, how many have tcp.flags.reset set. Report all three counts in a table.
q5- Which statement is true about the TTL value of an IPv4 packet header? Select one: A. It denotes the data payload type that the packet is carrying. B. It specifies the remaining "life" of the packet. C. It determines the priority of a packet. D. It indicates that the packet has been fragmented.
Locate the first packet utilizing the TCP protocol in the packet capture. What is the value of the TTL (Time to live) field in that packet's IPv4 header.
You are required to access any 5 HTTP objects (among them at least one should be an html, image, video and pdf objects). You are required to capture the HTTP request messages and their corresponding HTTP response messages through Wireshark or any other sniffing tool. With reference to corresponding HTTP RFCs, explain each header line of both the HTTP request and response messages.
Use the nslookup command to determine the name of the authoritative name server for the iit.ac.in domain. What is that name? (If there are more than one authoritative servers, what is the name of the first authoritative server returned by nslookup)? If you had to find the IP address of that authoritative name server, how would you do so?
Look at the packets' list below. Which packets belong to the FTP session? Please provide the packet line number for the FTP session by auditing the list. (e.g. answer like Line number 1-5, if FTP session packets are in a sequence ranging 1 to 5, or answer line number 7 if a packet appears/shown on its own amid other non-FTP session packets). You can select and copy the packets and then paste to a Notepad (text editor) or WordPad for inspection. Hint: not all packets are FTP session. Labels are given below (e.g. First Set/Range FTP Packets, etc): 1) 22:47:38.436811 IP 192.168.231.130.43492 > 23.217.196.4.443: Flags ack 4529, win 42340, length 02) 22:47:38.437011 IP 23.217.196.4.443 > 192.168.231.130.43492: Flags ack 1517, win 64240, length 03) 22:47:38.528426 IP 192.168.231.130.54561 > 192.168.231.2.53: 7444+ A? ftp.kerne.org.

Using Wireshark, capture a DNS request-response exchange on a real network. Submission: Submit a snapshot of a filtered Wireshark view that shows the request and response alone, and upload the pcap trace you collected.
iP protocol is one of the most common protocols operating at the network layer. Write a report minimum 2000 words explaining the options field in IPv4 header, your report should highlight the main difference between IPv4 and IPv6 protocol headers as well.
Which of the following statements is/are correct?I. The fragmentation is applicable for data in the datagram but not for header.II. Reassembly of the fragments must be performed at the destination because, the intermediatenetworks may have different maximum transmission unit (MTU) sizes.III. In the IP header, the time-to-live (TTL) field is invariable.(A) I and II(B) I and III(C) II and III(D) All are correct
