Credit Card Charge - Don't know what for?

Our business credit card was charged $51.99, but we don't know what it is for.  When I looked at an old welcoming e-mail from 2013 from AVG, it says at the bottom that it is in response to a request from IP address 194.213.42.17 - I checked to see if that was our old IP address from that time, but the IP lookup shows that address is located in the Czech Republic??  How can we find out what this charge is for and for what computer IP, because if it is for that IP address then it is an error as we are located in Northport Alabama?  Thank you for your assistance.
