First of all, yours is dynamic ip, which means that ip will change and you can't do binding mapping directly.
Also, you said that ip starts with 182. 100. I don't know whether you got this from the local machine or you found the export ip. If it is not on your local machine, then you can't map it to 182.438+000, because it is on the operator's equipment.
In addition, if your mapping is port 80, you have to file it before you can get through.
Solution:
Because I don't know housewives, there is a premise that this housewife software supports domain name access or other communication, which means that ip+ port is not the only form.
Then you can set up a router to assign a fixed intranet ip to your host, and then you can install a NAT 123 software on the server for dynamic domain name resolution.
Refer to this experience for specific operation: dynamic ip mapping.
hope this helps
