The fiber optic internet line has been opened at the Shin-Yurigaoka office. IPv6 didn’t work, so we had to try and error, but suddenly, on the third day after opening, we were able to connect successfully with IPv6. Considering that we were able to connect successfully with IPv6 just one day without changing any settings, I wonder if the ISP did any setting work for 2-3 days after the construction. This is the second time we’ve seen a similar phenomenon.
IPv4 has speed delays during busy times such as the evening, but IPv6 is comfortable with a constant download speed of around 200Mbps.
IPv6 is comfortable
