Ok so I wasnt sure of the appropriate section to post this in so I hope here is fine. I am a newb in the blackhat and hacking world and im sure this is a very newbish question but when visiting a website or doing any kind of online activity when is your IP logged or documented? For example, as soon as I type in the url and go to that website, as soon as I download an application is my IP immediately logged? My situation is that I just installed a bitcoin client, for which I would like to stay as anonymous as possible. I installed the client without changing/hiding my IP or MAC in any way. I have not created an account yet. Has my IP already been compromised if I use this client? Another situation being when signing up for an account on a forum like this one or anything else that requires account creation. If I created the account on my real IP and then say used a VPN or TOR and went to a local coffee shop to use the account, would somebody tracking me still be able to find me because at one time I did use the account on my real IP address? Thanks in advance for your patience with my ignorance in this area.
