TOR and VPNs can leak your IP address, or leak DNS requests to the ISP. Some software may not work well with TOR and leak your IP address (TOR claim that torrent software will leak your IP address when you use TOR. Windows can also leak IP addresses, while using VPNs (Google DNS leak). And if someone thinks I'm talking about torrenting, or I am supporting the use of illegal downloading; torrenting has many legitimate uses, and is used by many people to download opensource software, such as Linux distributions, and it's also useful for sharing large amounts of YouTube footage with people you're collaborating with, as you don't need to buy a server to host files. Also, VPNs are not specifically for torrents, but one of their main uses is encrypting your data, while using public Wi-Fi. All data you use through Wi-Fi can be viewed by anyone else using the same router with a computer or phone; VPNs encrypt this information, keeping your passwords safe.[DOUBLEPOST=1370190743,1370190584][/DOUBLEPOST]Haha, we're a little off-topic here, sorry about that.
