I am outside of my home network provided by Comcast.  I would like to find out what the most recent global IP of my home router was.  I have my laptop which was very recently connected to it and my Android Phone that was also connected a few hours ago.

 

I would like to find a log file, a system event... something which tells me what the public IP of my home Wi-Fi router was the last time that I connected to it.  It is a Windows 7 laptop.  Any help would be appreciated.

 

The why isn't terribly relevant:  I installed TightVNC at home and redirected the appropriate ports to an internet computer running the server.  But I forgot to find out my home router's public (world-visible) IP address before I left.

 

If the basic OS hasn't stored this information anywhere, there are some other things that would have reached to the outside world while it was on my home network which may or may not have logs.  Steam, battle.net, Chrome, Chrome Hangouts, Watchguard Mobile VPN, remote desktop over the VPN...  and an android phone.

 

I have not found this info in the basic OS.  

Pretty much expect to fail as the only thing I know which works is tracert from inside the target network.

Steam nor Battle.net seemed to be logging anything other than the valve and battlenet servers that they reached out to.

Not sure what you're trying to accomplish, but ...

If you were using DHCP, and still are on the home router, then the IP addy that the world sees can change every time the lease is renewed. If you need a fixed address then you probably will have to purchase a Static IP.

 

I get it now, my comment is nonsense, belay it.

The Security logs maybe could have it, so this might be of help ... http://en.wikipedia.org/wiki/Windows_Security_Log .

Yeah, I'm done with this for the afternoon and I'm soon to be driving back home where the answer is easy.  Didn't see any IP addresses in the security log.

I figure after I get home I can scrub the computer for the actual number and see if it appears in any of the logs/registry/text files on the computer.

As for TightVNC and a long-term solution for a static IP..  I might be able to do something more hacky... like a duck.  Errr.  DUC
