And that "problem" is easily bypassed, Para, and that is before we look at the "location" of IP addresses which can vary greatly depending on your ISP. Add in the small matter of most IP addresses being "dynamic" and you see that actually tracing an IP address is of no use to the scammers.
For example, a quick look at different "IP Tracers" has, so far, given my location as Antwerpen, Wilrijk, Mechelen, Heist-op-den-Berg and Kapellen. Now, as you can see, only one of these is right and that is for me. I've seen IP addresses in the UK being reported as somewhere hundreds of miles away, in all parts of the country (someone in London can have their IP being reported as being in Liverpool, for example).
So, sorry, but these people tracing your IP address is something that is useless to them. If they traced mine, as I did using different online "services", they would believe I was in a different area from where I actually am (since most results were saying "Wilrijk) and that is no use to them in the big scheme of things because all they want is certain details about your bank account. Also, since these details, as Capetonian rightly pointed out, are being sent via an ONLINE FORM and NOT BY EMAIL then being able to "trace" the IP address from an email is irrelevant and, as I have just pointed out to you, useless as far as the scam goes.
