What is IPv6?

IP stands for Internet Protocol and v6 denotes it's version no 6. It is also known  as IPng  that stands for  IP Next Generation. At present  the second version of the Internet Protocol is being  used usually  in the entire world. The first version, IPv4 had been used earlier whereas IPv5 was a different  sort of  protocol that intended  to  support  video and audio but not  for  addressing  purpose.

IPv6 is the advance version of  IPv4 mainly in the form of  address that is available for network device. IPv6 emerges in 128 bits  in each protocol  that allows 3.4x10^38 addresses. On the other hand IPv4 addresses have 32 bits in them that have the capacity of  four billion addresses. The IPv4, previous version of  IPv6 has upgraded for multicasting that delivers the data stream to multiple destinations. Multicasting transmit the data from one host  to many  hosts at the same time without  duplicating. besides this two types of addressing are unicast and multicast that are standard practice for the IPv6. IPv6 has mainly developed for mobiles that have higher level of  built-in- security.
