NTT DOCOMO starts the "IPv6 Single Stack System", which allocates only IPv6 addresses to docomo terminals."Prior to domestic telecommunications operators operating using conventional IPv4 addresses, we will respond to the IPv4 address depletion problem."
Switch the essential IP addresses for network communication to IPv6 in earnest.Until now, DOCOMO has adopted the "IPv4/IPv6 dual stack method", which allocates both the conventional IPv4 address and IPv6 address, but in the future, if the communication destination is an IPv4 address, it will be converted and connected.The /DNS64 method and the 464XLAT method enables only the IPv6 address.
Initially, 31 models, including docomo smartphones and data communication terminals, are supported.The terminals are gradually expanded, and all docomo terminals released after April will be the IPv6 single stack method.Even after the introduction of the method, the user's communication is not affected, and no settings are required or application.
With the increase in IoT equipment and the spread of 5G, the IPv4 address is lacking worldwide.For this reason, DOCOMO promotes IPv6 addresses that do not have to worry about depletion.We will promote the IPv6 address of Japanese mobile communication infrastructure.
