IPv6 is a protocol for giving computers ip addresses, unlike IPv4 which was a 32 bit address IPv6 is a 128bit address that means it can have a greater number of IP address combinations. currently IPv6 is only optional because only a few websites support it (i.e. haven't yet moved to use IPv6). The concept of IPv6 has been there for a long time, initially no one expected that IPv4 address will ever get over. But i guess they are and thus the shift to IPv6
