You will learn about fragmentation, and how large content is broken up, spread across a sequence of many packets, and reassembled at the destination. We'll also talk about some of the perceived hazards of this fragmentation process.doi:10.1016/B978-0-12-811027-0.00007-2Walter Goralski...

IPv6 and IPv4 IPv6was designed to be the next-generation protocol that fixes the limitations and flaws inIPv4. Sadly, since these two protocols cannot communicate with each other, IPv4 will not become obsolete anytime soon. Here are the key differences between these two protocols – ...
However, networks are developing faster and there is an acute shortage of addresses, prompting the IETF to propose IPv6, IPv7, IPv8, and IPv9 drafts in the hopes that one of them would replace IPv4. After thorough discussion, the IETF finally chose IPv6 to replace IPv4, eliminating IPv7, ...
Thanks to native IPSec, IPv6 provides two security headers which can be used separately or together: the Authentication Header (AH) and Encapsulating Security Payload (ESP). Authentication Header provides data-origin authentication and protection against replay attacks, while ESP delivers connectionless ...
IPv4 over IPv6 Tunnel Header To ensure the transmission of IPv4 packets over IPv6 networks, append IPv6 headers to IPv4 packets to encapsulate the IPv4 packets into IPv6 packets. Figure 19-1 shows the standard protocol-defined format of an IPv6 header. Figure 19-1 IPv6 header format Table...

IPv4 also allows both the sender and the post office (routers) to break down large packets into smaller pieces if needed. On the other hand, IPv6 headers are like standardized envelopes with a fixed size. They have only eight fields of information and no checksum. IPv6 only allows the sen...
Custom HTTP Request Headers Override request headers, e.g.: Content-Type: application/json Cookie: name=value; name2=value2 User-Agent: Mozilla/5.0 IP Mode IPv4 only IPv6 only Force IP Address Override the IP address to which the URL hostname resolves. Useful to test specific servers...
Today, the internet is like a massive highway, with users acting like thousands of cars driving up and down. Since each of those cars needs a license plate, every user connected to the internet needs an address. These addresses come in two versions:IPv4 and IPv6. ...
