If I understood well the initial IP payload should be fragmented in several smaller packets. Hence the first IP packet has the TCP/UDP header and probably the beginning of the UDP/TCP payload. The second one has the next part of the UDP/TCP payload, and so on until the whole UDP/TCP message is sent.
the Internet Protocol part of the packet in the packet details window. What is the IP address of your computer? 2. Within the IP packet header, what is the value in the upper layer protocol field? 3. How many bytes are in the IP header? How many bytes are in the payload of the IP datagram? Explain how you determined the number of payload bytes. 4. JSAN | Free Full-Text | IETF Standardization in the Field Smart embedded objects will become an important part of what is called the Internet of Things. However, the integration of embedded devices into the Internet introduces several challenges, since many of the existing Internet technologies and protocols were not designed for this class of devices. In the past few years, there have been many efforts to enable the extension of Internet IP fragmentation is an Internet Protocol (IP) process that breaks packets into smaller pieces (fragments), so that the resulting pieces can pass through a link with a smaller maximum transmission unit (MTU) than the original packet size. The fragments are reassembled by the receiving host. IP fragmentation attacks are a kind of computer security attack based on how the Internet Protocol (IP) requires data to be transmitted and processed. Specifically, it invokes IP fragmentation, a process used to partition messages (the service data unit (SDU); typically a packet) from one layer of a network into multiple smaller payloads that can fit within the lower layer's protocol data unit For the second of those, if the "Fragmented IP Protocol" packets have a bad IP header checksum, turn off the "Validate the IPv4 checksum if possible" preference for IP.

IPv4 protocol performs fragmentation: a router breaks the datagram up into smaller individual pieces called frag-ments. Each fragment has its own IP header, which is a replica of the original datagram header. Thus each frag-ment has the same identiﬁcation, protocol, source IP ad-dress, and destination IP address as the original IP packet.

If a PC is preparing an email to send, it will take the transport segment and encapsulate it into an IP packet. An IP packet can theoretically be up to 65535 bytes long.
