FYI - You log onto any Web site they have your "info" of who you are and where your logging on from. FYI
This is not necessarily true, when you log onto a website it can log a record of any transmission with the IP address and it is possible for it to get host header information as well but nothing "personal" unless you give it to them or you use an outdated or insecure client. An IP address tells them what network you are on, i.e. 123.123.123.123 may resolve to dhcpclient123.sometown.s
omestate.randomisp.com. Unless the client has a static IP address (generally only used for servers) then their IP is dynamic and changes when the router or modem is reset or on a set renewal time. In order for them to find out from there who you are they would have to get the IP from the website, which requires a warrant (assuming they even log it), then they would have to call the ISP and find out what the MAC address of the router was that was leasing the IP address during the time period in question. This assumes the ISP keeps track of all the MAC addresses for the modems and routers they give out (they often are not recorded). They, of course, cannot do this without a warrant. The Holywood version of them immediately tracking you to your location is
not how it happens in the real world I assure you, in general if they
really want to know, it will take about a week to get all of the information assuming that it even exists in logs and records from the website and ISP.
Unless the website or the website's ISP is cooperating with them, law enforcement cannot tell even your IP address just by you being logged in while they are logged in.
