How to determine which country ip is from using local library?

Question

bash

Some introductory information
There is a large pack of ip in the file (100mb - 1gb), so it is not an option to find out ip through a request to third-party sites. Implemented the definition of ip and the scattering of country files on bash, now I decided to do it in the web interface.

Question: is there a package on nodejs to determine from which country ip with local library? Or is it better to pass a file from ip to a bash script so that it does the job and transfers the files back to NodeJS?

I’ll add an addition, write the answer to those who really used it, I know how to use Google, I’m also able to draw logical conclusions. No offense...

PS Of course, I would like to do it completely in NodeJS, so as not to depend on the OS.

All ip addresses have the first 2 numbers 111 . 111.111.111 - are an indicator of the country, providers often indicate the country in whois, here, you can write a module, and fill in the range of these numbers and compare with countries. Create some dictionary.
