Why we need IPv6 ?

IPv6, the successor standard to IPv4, for existing networks that currently use IPv4 communications could solve the basic problem of the availability of only approximately 4.3 billion IPv4 addresses. Ceasing use of IPv4 addresses and only using IPv6 addresses, however, is impractical and thus maintaining an environment that enables mutual communication between IPv4 and IPv6 […]

Difference between IPv4 and IPv6

     On the Internet, data is transmitted in the form of network packets. IPv6 specifies a new packet format, designed to minimize packet header processing by routers. Because the headers of IPv4 and IPv6 header packets are significantly different, the two protocols are not interoperable. However, in most respects, IPv6 is a conservative extension of IPv4. Most […]
