IP address logged by my Netflix account after the individual hacked into and locked me out of my account. Individual also changed my account settings to the most expensive plan, which allows multiple people (profiles) to watch, and several profiles were added. The name on my account was changed to "Juan". I contacted Netflix to have my account restored, so I was able to see the various IP addresses used. I will report all of them as well.
