'''IPv6''' was created as a solution to the inevitable threat posed by the exhaustion of IPv4 addresses. The [[IETF|Internet Engineering Task Force]] was involved in its creation as it decided to explore new technologies by expanding the address capability of the Internet. <ref>[http://playground.sun.com/ipv6/ IPv6 and IETF]</ref>IPv6 does not guarantee a sufficient quantity of addresses but it definitely enables an efficient aggregation and allocation of rooting prefixes for routing nodes.

'''IPv6 '''has 340 undecillion (340 x 10 ^36) addresses. To put this in perspective: consider our galaxy, the milky way has estimated 300 b llionstars (300 x 10 ^9). This is to say there are a trillion trillion trillion IPv6 addresses than stars in our galaxy.

The main challenge facing the deployment of '''IPv6 '''however, is the lack of backward compatibility between '''IPv6''' and '''IPv4'''.
