YES

As long as the ISP that owns the IPAddress gives it out. For example there
was a person in Sweden who sold porn on the Internet and put the money in a
bank outside of EU where no taxdeparment could reach the money or even know
about the money. The person used International web sites that couldn't be
tracked to the person. However the person made the mistake to send our
emails to the users and that was through the emails the tax department could
find out that he had withold about $900.000 for the tax department, He had
to pay the tax for all the money and also had to spend 2 years in jail as I
recall the story.
