DNS Server IP address Update

Question

I am new to Node.js and using the node.js I want to get the DNS server IP address of my connected interface.During searching I got on the node.js documentation that the 'DNS' module can be used for it and its function

dns.getServers() will return the address,

dns.setServers(servers) will set it.

when I call these functions and check it on console I show correct result but my problem is that I want to update it on the network interface setting in my Desktop PC system preference settings.

I also search that for getting the interfaces information in node.js,the 'OS' Module will be used and its function os.networkInterfaces() gives the interface details.

I think that there should be relation between these two modules to update the DNS server address to the interface.

Is it possible to do it or am I using a wrong approach.. please give some guidance and help.

Thanks

Answer 1

You will need to update the DNS of your network interface through the OS rather than Node.js

Any variables set in Node.js will not persist outside of that environment.
