I suggest you review the geo blocking technology. it works based on the user's location but it can be circumvented with vpn.

Have you taken a Shared Hosting Plan or you have taken a VPS or a Decicated Server...
As if you have taken a shared Hosting Plan then Owner use to Provide their Name Servers to setup in your Domain.
And in case of VPS/Dedicated Server, you have to create it via WHM > Basic Configuration and you also need to create Child Name Server in Domain control with the IP of your VPS/Dedicated Server...
Hope this will Help you..
I'm working on a project and stuck in the DNS Leak Tool, where I would have to perform the same task as http://dnsleak.com/ these website doing, is there any logic, where I can get fetch DNS server IP?
Really appreciate if you guys can help!

I think you just have to do something like this :
const dns = require('dns');
dns.getServers();
See documentation for more information.
Hope it helps.
Say I have a website http://mydomain.com. I'm setting up Jira and testing environment which are on the different server and IP address than the main website. Is it a bad idea to set them up as subdomains: testenv.mydomain.com and jira.mydomain.com?
I have seen this setting on many occasions and use it myself. I do not consider it a bad idea, on the contrary.
when i visit the github.com,and then get a tip like that:
You have a stale /etc/hosts entry for GitHub.com. Please remove that
entry ASAP!
And it confused me, as you can see below:
Can we get the visit source come form the hosts file and how it works?
If the answer is NO, i guess that the github.com know it because of the request ip is old, and then the website display the tip.
Sure the /etc/hosts file had been edited. I am in the CHINA, you know.
And thanks to look at this question.
No, the only relevant information the website gets is the IP address to which you've connected, and the Host: HTTP header saying what domain you are trying to access.
As you say, GitHub is presumably just detecting that you are accessing the wrong IP address, and assuming that you can't be using their real DNS records.
