IP6 vs IP4

Ip4 was insufficient for the modern internet. IPv6 is the sixth revision to the Internet Protocol and the successor to IPv4. It functions similarly to IPv4 in that it provides the unique, numerical IP addresses necessary for Internet-enabled devices to communicate. However, it does sport one major difference: it utilizes 128-bit addresses. With ip4 it utilizes 32- bit addresses meaning they all can't be public. With only around 4.4 billion addresses with ip6 their is most addresses than their is devices on the planet. so they'll never run out. The Take over of ip6 would mean - No more NAT (Network Address Translation) - Auto-configuration - No more private address collisions - Better multicast routing - Simpler header format - Simplified, more efficient routing - True quality of service (QoS), also called "flow labeling" - Built-in authentication and privacy support - Flexible options and extensions - Easier administration (say good-bye to DHCP)
