I am connected to Internet through an ADSL modem, my ISP gives me an IP address, does Ubuntu log this IP address somewhere?
How can I configure Ubuntu to log the IP address?
Or you can do it yourself, using curl to access a number of online services that respond with your public IP address.
Some of the services:
Example:
curl icanhazip.com will output to terminal
curl icanhazip.com > my_public_ip.txt will create or overide a txt file named my_public_ip.txt with the IP.
curl icanhazip.com >> my_public_ip.txt will append the public IP every time the command runs.
You could create a small script to run the check and even add it as cron job to run say every time the machine reboots or at some intervals.
The simplest version could be:
#!/usr/bin/env bash
curl icanhazip.com >> my_public_ip.txt
