Windows Batch - How to get the external IP into a batch-file variable

Question

I am making a program that checks if a user\'s IP is a certain IP address.

Currently, I created a successful internal IP version:

@echo off
set userI         


        

Answer 1

To get your public IP without additional parsing do this:

curl "http://api.ipify.org"

EDIT:

This version is more reliable across windows language versions:

for /f "tokens=3 delims== " %%A in ('
nslookup -debug myip.opendns.com. resolver1.opendns.com 2^>NUL^|findstr /C:"internet address"
') do set "ext_ip=%%A"
