IPv6

The  internet  engineering task force begin  the effort to develop a successor  protocols  to IPv4 in the early  1990 is an internet  layer protocols  for packet  switched  internet works. IPv4 was the late version which was having  some limitations that why  need to develop  another version name IPv6. IPv6 provides  much larger address space than IPv4. It has  also  provided  flexibility in  allotting addresses and routing  traffics. The  adders format  is extended form 32 bits  to 128 bits to avoid  address exhaustion and also  simplifies  aspects of address assignment  and renumber according to the changes in internet connectivity.
