Yes dear as i mentioned its nothing to with the generation change. Yes true we cant use use IPV4 for the the 5G because now IPV4 capacity is not enough to serice in future due to its limitations in the total adress generation. So we are using IPV6 as a pro feature so we can use 340 undecillion addresses enough for the coming 1000 years.....

So i think its clear now we can't use 5G without IPV6 network addresses but its nothing to do with 5th genration technology except for adress generation.
