How do you check if an IP address is a proxy?

How do you check if a proxy is used?

I would like to know if there is any way of getting an indication if a proxy has been used with the Google Maps API. Does anyone know if google provides that information in some way? thanks. Google Maps v2 doesn't provide an API against the raw V3 protocol, if that's what you're asking for. You might want to take a look at the HTTP Live Headers tool after submitting your request, so you can see what the server is sending back. Also, you could take a look at the requests being made to explore what data is being sent.
