IPv 6 Addresses

IPv4 has valiantly served the Internet from the early
days, when only a handful of devices were interconnected
at college campuses in the United States for research
purposes, to today, when billions of devices are
interconnected and exchanging massive amounts of data.
The longevity of IPv4 and the addressing scheme it
defines is a testament to how robust and scalable IP
actually is. Even so, IPv4 faces limitations, including the
insufficiency of 32-bit addresses, the need for the IP
header to be streamlined and simplified, and the need for
security embedded in the protocol rather than
implemented as an afterthought.
