That seems to be the point where your ISP hands off your connection to NTT. You can call your ISP to learn more about that point specifically and ask them routing questions. But if NTT controls your connection and routes you elsewhere that might be SE's ISP instead. In which case a moderator might be able to forward this information to NTT. But I don't see any action taken on their behalf.

Contact your ISP and ask about the hand off point. See if you can get any info that you can post here to help the moderator team.
