What is IPv6?

IPv6 means Internet protocol version 6 . This is the second version of the Internet protocol, which is generally used throughout the virtual world. The first version was IPv4. The IPv5 was a different kind protocol that was supposed to support video and sound rather than universal addressing. IPv6 is also known as IPNG that means IP Next Generation .

One of the main upgrades in IPv6 is the number of addresses available for network devices. For example, every mobile phone or other type of electronic device can have its own address. IPv6 allows addresses 3.4x10 38 . This is mainly due to the number of bits in every protocol. IPv4 addresses have 32 bits, allowing a maximum of four billion addresses. The version 6 addresses have 128 bits. However,

IPv4 is still a protocol for most of the Internet. The transition will be stable and IPv6 is the future of Internet addressing, mainly because experts in the field believe that you will be almost available addresses available.

Another example of the IPv6 upgrade is multicasting, which is standard in this version, but only optional in IPv4. Multicasting adds a data flow to multiple destinations at the same time, without duplication, unless required. These features are not supported by IPv4. Two other types of addressing, which are a standard practice for a newer version, are Unicast and Anycast. The first is the transmission from just one host to just one more host; He comes from one host to the nearest of many hosts.

IPv6 also has two other significant advantages over IPv4. It offers a higher level of built -in security and has been specially designed with regard to mobile devices. Security comes in the form of IPSEC, which allows verification, encryption and compression. Mobility comes in the form of a mobile IP, allowing roaming between different networks without losing the established IP addresses. Both of these features are IPv6 requirements and are therefore designed to be ZabuDown for each magazine, addresses and network.
