Dynamic IP address change or hacker attempt

So I tried to log into my account today and it said there was an attempted log in from a different location, it told me this and made me wait until I allowed the access from the email sent at that moment. Why did this happen, should I be worried, or did my dynamic IP address supplied via my ISP’s dns server change and now I had to re-authenticate my account? Due to the way dynamic addressing happens I now how to re-authenticate every so often when my ISP decides to change my IP address, how will I know this is what happened or if it was a hacker attempt?

Not to make a sweeping statement, but generally attempts to hack an account come from a distant location, not next door, in the next town, or even across the state. A player from the UK had auth requests from England, Wales, and Scotland. They were all ok — all his log-in attempts — but his ISP was using a broad list of IP addresses.

I’m not a security specialist, but I would be far more worried about a log-in attempt from China (the most common location from which compromise attempts are made) than I would be from one a few hundred miles away.

However, if you are at all uncomfortable with the access attempt, decline and restart the log-in attempt and see what happens.
