DNS Records; for type A, Name, Data: what ID is used, cmponet ID eg NodeMCU or local internent provider ID?
Your example: smarthomecourse.com, value= 199.3********
I don’t know what to use?
I’m not sure I understood your question.
See page 168, bullet number 8). You should get an IP address on the value field. That’s that value you should use.
Depending on the domain provider, you may have a section called “Data”, you should paste the IP adddress you got on bullet number 8) on that field. It has nothing to do with the NodeMCU IP address.
Let me know if this is clear.
