ASAHI Net’s fixed IP address had become a dynamic global IP address.

When I checked the settings page for ASAHI Net’s fixed IP address option, it was clearly written there.

• 固定IPアドレスオプション｜プロバイダ ASAHIネット

Connection username*1 f.ASAHI Net ID@atson.net Example: f.ab4t-ash@atson.net f.u1234ab567c@atson.net f.c1234ab567c@atson.net

For each fixed IP address option contracted ASAHI Net ID, if you set it as ASAHI Net ID@atson.net (example: ab4t-ash@atson.net), a dynamic global IP address will be assigned.

The cause was that I had specified ab4t-ash@atson.net when I should have set it as f.ab4t-ash@atson.net.

That’s all from the Gemba.
