Tracking dynamic IP's from the ISP



  • Is there a suggested method for tracking the IP that I get on the WAN side from my ISP? This is purely curiousity but I'd like to have a log entry I could search for or some method to see over time what IP's are issued from upstream.

    Set up email notifications System -> Advanced -> Notifications

    Install mailreport System -> Package Manager -> Available Packages

    Run the following ifconfig pppoe0 from an email report every 24 hrs

    pppoe0 is my WAN interface.

    Or set a cronjob to run ifconfig and output the config to System logs using ifconfig pppoe0 | grep inet | logger -i -t pppoe the -t could be whatever you wanted to call the process name

    You can just filter the logs by IP change and you will see changes listed for the time covered by the logs:

    That does show all 'WAN' type connections so an OpenVPN client connection also in my case there.
