Most of you reading this will be thinking to yourself WTF is IPv6. IPv6 (Internet Protocol version 6) is attempting to replace what we currently use, IPv4 (IPv5 was experimental). IP addresses in IPv6 are very different to the current ones we use. IPv4 only has 4,294,967,295 possible addresses, however many of these are reserved for such things as LANs and Multicasts.

Below is standard IPv4 address representations:

Dotted Decimal (normal): 207.142.131.235
Dotted Hexadecimal:0xCF.0×8E.0×83.0xEB
Dotted Octal 0317.0216.0203.0353
Decimal:3482223595
Hexadecimal:0xCF8E83EB

Currently, IPv6 addresses are written as something such as 2001:0db8:85a3:08d3:1319:8a2e:0370:7334 . Which one is easier? An IPv4 one. However, domain names are fully supported in IPv6. Not many ISPs provide an IPv6 tunnel.

Not many sites are available on IPv6, however if you wish to access one which is I suggest you use the IPv4Gate, it is the bottom collection of sites. The top one is for IPv6 users to access IPv4.

Don’t worry too much if you don’t understand, IPv6 is only due to really replace IPv4 in 2025.
