First of all, you should check whether the IP address specified in the letter matches your current IP address. We advise you to use a free geolocation service like this one, for instance.
Important: due to technical restrictions such services cannot specify the absolute location of a required IP address, but in common they allow to find a country, a city and an ISP provider servicing that IP address. Anyways, this shall be enough to clarify whether it was your IP address in the information message.
