While IPv4 and IPv6 are used to identify Internet users on a network and to enable communication between computers over the Internet, they are not the same thing.
IPv4 addresses are the most widely used by Internet users and have been around since the early 1980s. They are depicted using dotted decimal notation, in which each part is a group of 8 address bits, forming a 32-bit addressing scheme.
The possible combinations of IPv4 addresses are limited, and you can only combine them in over 4 billion (2564) ways. In the early days of IPv4, that number seemed endless, but that changed in 2011 when the global Internet Assigned Numbers Authority (IANA) issued the last block of IPv4 addresses. In 2015, it was officially announced that IPv4 addresses no longer existed in the US.
Although IPv4 addresses have been depleted, the protocol still carries most of the Internet traffic due to the continued use of IPv4. Network Address Translation (NAT) is a process that allows multiple devices to use a single IP address, helping to prolong its use. Another reason you can still use IPv4 is that IP addresses can be reused.

These methods are just ways to continue using IPv4, but there is a solution to the problem of running out of IP addresses; IPv6.
Although IPv6 is the solution to the problem of exhaustive IP addresses in a city, it has been around for a long time and its first goal is to replace IPv4. IPv6 uses hexadecimal numbers, which are separated by colons into 8 16-bit blocks, forming a 128-bit addressing scheme.
The number of possible combinations for IPv6 is also limited as for IPv4, but in this case the limitation is different. The theoretical number of possible combinations and IP addresses that can be generated using IPv6 is 3.4×1038. Yes, this is a huge amount, but the day will come when it will be depleted like IPv4.
Requirements for IPv6
To use IPv6, you need IPv6-compatible operating systems. Windows Vista and other newer versions of Windows, Linux and Mac OS X are IPv6 compatible.
Many routers today do not support IPv6, and it is important for you that your router supports this protocol. To be sure, check the specifications of your router, and if you want to make a new purchase, choose one that supports IPv6.
Even if you have a compatible OS and a router to use with IPv6, if your ISP doesn’t provide you with an IPv6 connection, you won’t be able to use it. Thus, your ISP should provide you with the specified connection.
Configure IPv6 in the city
in the city, go to the notification area and right-click on the network icon. Click Open Network and Sharing Center. On the left side of the screen, you will see “Change adapter settings”. Press here. Right click on the correct network connection and select Properties. You will see a list under the heading “This connection uses the following items.” Check the box next to “Internet Protocol Version 6” and click “Ok”.
