Has someone hacked my Facebook Account?

[AnswerGuru21]

So I went to my security settings on my Facebook Account and looked at my most recent "Active Sessions" and have seen one location pop up repeatedly that I do not recognize.. I am from the Midwest, but have been in Texas for the last several months, and the location says its being accessed from Livingston, NJ. I have never been to New Jersey in my life. It says it's being accessed by Android (which I have and sometimes use to access FB myself), and never any other device, while I use my phone, computer, ipad, etc. However, when I hover my mouse of the location to see the IP address, it is waaay too long to be a regular IP address, and also contains letters. In total, it has 28 letters and numbers, separated by colons instead of periods. Have I been hacked? Is this some kind of computer virus? Or is my account getting confused when I access it via Android. I find the whole thing very suspicious, and will likely change my password.
