Valid IPv6 Address

It can be said that the the major force behind the development of IPv6 is the aim to increase the IP address pool. In fact, IPv6 is a conservative extension of IPv4. It uses a 128-bit address which can give out 340,282,366,920,938,463,463,374,607,431,768,211,456 available internet addresses (and we're not kidding). This is enough to give 100 IP addresses or more to every person living in the world. What makes this different from IPv4? The old IPv4 uses 32-bit addresses. IPv4's address pool is obviously dead-beat smaller than that of IPv6 (this is the reason why there is an IPv4 address exhaustion problem, anyway). IPv6, unlike Ipv4, uses 8 groups of 4 hexadecimal digits, with each group representing 16 bits and separated by ":".

IPv6 addresses, however, are very hard to comprehend. Before, it's possible to understand the maths behind IPv4 addresses even just by memorizing its various classes. Since IPv6 uses 128-bit addresses, as we've already said, this “traditional” way won't work anymore. How will you be able to understand IPv6 addresses? Go use Google and find an IP address calculator. That's the easiest way. Anyway, dealing with IPv6 addresses should be the job of your network manager. How IPv6 can help alleviate the address exhaustion problem is the most important thing to take note here.
