Public IP#
I am using China Unicom, so I have relatively more IPv4 resources, so it will be available soon after dialing 10010. However, when I installed broadband before, I asked the broadband technician to change it to router dialing. As a result, although the optical modem is in the state of a public IP, the router and the local machine are not. At the same time, there was a mistake with 10010, and they mistakenly opened the public IP service for another person (possibly another fiber optic cable in the same room, because both fiber optic cables were opened with my ID card and have the same address).
After China Unicom opens the public IP service, you need to restart the router (i.e., power off for 3-5 minutes and then power on) to obtain the correct public IP. After struggling for an hour or two, I finally got the long-awaited IP. I can now set up a server at home and do whatever I want.
IPV6#
After switching from router dialing to optical modem dialing, the optical modem backend does not provide an IPV6 address by default... so I can only use the super administrator's permission to enter the backend and modify the relevant settings.
Super administrator address: http://192.168.1.1/cu.html, password is CUAdmin
