This isn't the correct place either.
We mainly focus on questions that solve practical problems.
Your example questions are far too broad to be answered and would depend on quite a few assumptions. For example: country, definition of ISP, infrastructure and more.
If you did provide enough information for us to answer your question it would in all likelihood be Too Localized instead, and still not solve a practical problem.
I can't say that this question belongs on any SE site that I'm familiar with.
