Internet protocol versions — A review

Internet contributes to effective communication and exchange the information between people around the world through the easiest and fastest way. TCP/IP (Transmission Control Protocol/Internet Protocol) is a protocol which allocates address to each device for recognition and dispreads packets on the Internet. Over the years the IP has been changed because of user's requirements. The first IP has been used broadly is IPV4 (Internet Protocol version 4) but it has encountered some problems with growth the number of user who use Internet. Internet Protocol version 6 is the next generation of Internet Protocol which has been used globally. IPv6 eliminates the most important problems of IPv4. This study briefly investigates the key features of IPv4 and IPv6.
