Discuss Internet Protocol Version 6, next generation version of the internet protocol. Includes improved address space, quality of service and data security.
Internet Protocol version 6 (IPv6) is Internet Layer protocol for packet-switched internetworks and the Internet.
IPv6 has a much larger address space than IPv4. This is based on the definition of a 128-bit address, whereas IPv4 used only 32 bits. The new address space thus supports 2128 (about 3.4×1038) addresses. This expansion provides flexibility in allocating addresses and routing traffic and eliminates the need for network address translation (NAT). NAT gained wide-spread deployment as an effort to alleviate IPv4 address exhaustion.
IPv6 also implements new features that simplify aspects of address assignment (stateless address autoconfiguration) and network renumbering (prefix and router announcements) when changing Internet connectivity providers. The IPv6 subnet size has been standardized by fixing the size of the host identifier portion of an address to 64 bits to facilitate an automatic mechanism for forming the host identifier from Link Layer media addressing information (MAC address).
Network security is integrated into the design of the IPv6 architecture. Internet Protocol Security (IPsec) was originally developed for IPv6, but found wide-spread optional deployment first in IPv4 (into which it was back-engineered). The IPv6 specifications mandate IPsec implementation as a fundamental interoperability requirement.
I was just looking thru the settings of my Airport Extreme base station router and came across IPv6. There's a check in the box that says "Block Incoming IPv6 Connections". What exactly changes if I uncheck that box and allow the incoming connections? Are there certain internet applications that it would help or hinder? It says something about how IPv6 increases the address size or something?? Any networking pros please advise.Thanks
IPv6 is sometimes called the Next Generation Internet Protocol, or IPng. Even though the Internet is seen as a relatively new technology, the protocols and technologies that make it work were developed in the 1970s and 1980s..IPv6 eases connectivity for secure next-generation devices..it has dual capabilities provide the company's customers with industry standard approved technology..
IPv6 stands for Internet Protocol version 6. It is the second version of the Internet Protocol. One of the main upgrades in IPv6 is in the number of addresses available for networked devices. IPv6 allows 3.4x10^38 addresses is mainly due to the number of bits in each protocol.
IPv6 means Internet Protocol version 6.IPv6 is 128 bits, can support up to 2128 addresses to fulfill future needs with better security and network related features.
