I’ve recently had problems with my internet service. My DSL router is apparently re-syncing causing my public IP address to change. Apparently my ISP uses PPOE rather than DHCP, and apparently PPOE does not allow “Reservations”, which allows a client computer to use the same IP address if it reconnects within a given amount of time. Your home router uses DHCP, which does do reservations, so your computers LAN IP address does not change if the computer connects every 24 hours, which I understand is the default “Reservation” time.
Re-synching is not only a problem because the internet is out for a short amount of time, but also because the IP address change causes some games to require that you “Verify” your IP address by reporting a code that is sent to your email account. This is obviously an issue if the Re-Sync happens several times per day.
After quite a bit of research I found a windows service that logs the Public IP address to the Windows Event log every 15 minutes. I run one of my windows systems all the time, since it’s running Carbonite, so this system will run the PublicIpLogger program.
If you want to use the program, it’s on GitHub here. This is the forum post that mentions this program.
From Github, download the setup.exe file and run it. Then you can enter “view event log” into Cortana and you should see a choice to run the windows event viewer. The program logs your public IP address to the event log every 15 minutes.
As shown, under Application and Service Logs, find the PublicIpLogger events and there are a number of events that show the Public IP address, whether they have changed or not.
Enjoy,
