- In IPv4, the address format is a 32-bit numeric number that is frequently written as four octets separated by periods from the range [0, 255]. At the time of writing, Internet Protocol version 6 (IPv6), with 128-bit addresses, was gradually replacing IPv4. How many IP addresses may be assigned in IPv4 and IPv6 in theory?25 Which is the correct expression for the length of UDP datagram? UDP length = IP length + IP header's length UDP length = UDP length – UDP header's length UDP length = IP length – IP header's length UDP length = UDP length + UDP header's lengthIf the flag section of the TCP packet contains 00010000, what type of TCP packet will that be?
- Why is there a header length field in the TCP header but not in the UDP header?The udp header is as follows: 12 0300 0F 00 1E A3. The overall length of the udp is how long?Answers should all be in lowercase with no spaces between hex characters when hexadecimal is the answer expected. All hex values must start with 0x, which stands for hexadecimal and therefore include 0x in your answers. Q1: What Transport protocol is encapsulated in the packet trace? Answer: The Transport protocol is encapsulated in the packet trace is: Q2. What is the value in hexadecimal of the Destination port address? Answer: The value in hexadecimal of the Destination Port Address is: Q3: What is the value in hexadecimal of the Transport header Checksum? Answer: The value in hexadecimal of the Transport header Checksum is: Q4: What is the value in hexadecimal of the Sequence Number? Answer: The value in hexadecimal of the Sequence Number is: Q5: What is the value in hexadecimal of the Source Transport Port Address? Answer: The value in hexadecimal of the Source Port Address is:
- TCP is one of the most common protocols operating at the transport layer and providing reliable end to end devlivery. TCP header is a variable length header since it might contain OPTIONS field. Write a report explaining the different options that can be added in this field.The binary value of the total length field in the IPv4 packet is 110010. The binary value of the HLEN of the IPv4 packet is 0111. What is the length of the data unit of an UDP packet encapsulated in this IPv4 packet?IP datagrams on a specific network can carry a maximum of only 440 bytes in the data portion. A node on this network, running an application using TCP generates a TCP segment with 1,900 bytes in the data portion. How many IP packets are transmitted to carry this TCP segment, and what are their sizes (including the header of 20 bytes)?
