My IP address is wrong

I noticed this from time to time. Everytime I go to blogs or sites with a feedjit widget I see my source location is from a different region in my country. And when I surf for IP address locator add-ons its still the same. I don't understand why this is so. But it has been bugging me now. I don't know how to correct it. Should I contact my ISP about it?

Edit: It's fixed now. lol
