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 [email protected] Example: [email protected] [email protected] [email protected]

For each fixed IP address option contracted ASAHI Net ID, if you set it as ASAHI Net [email protected] (example: [email protected]), a dynamic global IP address will be assigned.

The cause was that I had specified [email protected] when I should have set it as [email protected].

That’s all from the Gemba.
