The Internet is a relatively new system, like all other systems, may need to be modified to function properly and to anticipate future problems. In this case it is an outdated IPv4 internet protocol and will not be able to satisfy future requirements. The Internet is growing bigger and growing day by day, IPv6 will surely scale up and become bigger than understood. Cisco Report (T. Hain) expects that available IP addresses will be exhausted within 4 to 5 years. In order to keep the Internet growing and acquiring new domains, we need to switch to this new protocol.
The simple answer is as follows. 1) Query the Internet service provider (ISP) for the IPv6 address (you can check if the address is included in this list). 3) Make sure your device supports IPv6. Most operating systems (including mobile phones) and most network devices support IPv6, but some devices and applications may not support IPv6.

New computer equipment and software may be displayed as "IPv6 compliant" in the package. Related information in the user manual, usually in the technical specifications section.
Even if the network moves from IPv4 address to IPv6 address, Internet service and online service will continue to function. Internet service provider (ISP) upgraded to IPv6, most PC operating systems support IPv6. However, many routers and servers currently in use do not support it, so it is difficult to connect a device with an IPv6 address to a router or server that supports only IPv4. During the transition period, ISPs, Internet content and application providers will take steps to ensure continued support for IPv4 addresses. However, due to incomplete or incomplete switching to IPv6, online services may be weakened or degraded. The speed of your favorite Web application may be reduced or communication between computers may become difficult. Privacy may be affected by functions, increased division and transmission of IPv4 addresses.
