I need to know which IP address I was using two days ago. Is there any log file in OS X that contains this information?
Update: And Chrome for Mac could store this information somewhere?

I had checked that post, but it doesn´t help. Gmail emails don´t store any more IP information– user2082695May 5, 2014 at 19:57

@user2082695 I added an answer on that to that question which may be useful to you.– Louis WaweruMay 5, 2014 at 20:27

I knew about that, I tried, but the information was going only one day back, so not enough– user2082695May 6, 2014 at 6:28

It's too late for you now, but you can get it to start logging things like this by running…
sudo ipconfig setverbose 1
…at every boot.
Then you can search for "network changed" in the All Messages ASL log stream in /Applications/Utilities/Console.app, or in /var/log/system.log[.#.gz], or in /Library/Logs/CrashReporter/com.apple.networking.IPConfiguration.log.[SomeDateString[.gz]]
From the possible duplicate:
Your modem/router might keep logs on which IP the DSL was registered to. Usually the modem's logs/UI is accessible by navigating to its IP through your browser.
My modem keeps a firewall log. You may be able to look at your modem to find out source/destination addresses and see it there.

IN the logs of my modem-router there are no information about the IP. May 5, 2014 at 22:00
