IPv4, which we have used until today, allowed about 4.3 billion IP addresses. With today’s launch, this number, the number of IPv6, will increase to 340 trillion trillion trillion. In other words, it can be expressed as 340,000,000,000,000,000,000,000,000,000,000,000,000. It stands out as a number that seems quite sufficient for the foreseeable future. Although I do not know exactly what it means, I think something nice happened.
