	IPv6 (IP version 6, RFC 2460) is the replacement for the current [[IP\|IPv4]] Internet. Why there is no version 5 is not known. The bonuses for IPv6 include 128 bit addresses instead of 32 in IPv4. This allows the [[Internet]] to grow so that every human on earth can have an IP address, as currently IPv4 only has space for only 4 billion IP addresses.

	One good thing to remember is that an IPv6 packet header is on a 64 bit boundary. So one has as part of the IPv6 header 64 bits data for things such as version and hop ~~count~~ and 128 bits source address and 128 bits destination address. In a hex dump the addresses are easy to identify unlike in IPv4.		One good thing to remember is that an IPv6 packet header is on a 64 bit boundary.
