IPv6

IPv6 is a networking protocol which is the successor to IPv4. IPv6 allows a huge number of IP addresses (Internet addresses) relieving the current concerns regarding the restrictions of IPv4 which only has room for 4.3 Billion (comparing this to the growing world population of around 6.5 Billion).

IPv6 addresses are normally written using eight sets of four hexadecimal digits, ie 2001:0db8:85a3:08d3:1319:8a2e:0370:7334 . This, compared to IPv4 using four sets of numerical digits, 192.168.1.1, shows the relative benefits as to the number of possible addresses. However this complexity requires more bandwidth.
