Smart DNS proxies like Unotelly, Overplay, Unlocator, and Unblock-US were a flash in the pan during Netflix’s war on proxies. After Netflix blocked connections from most VPN servers, many users switched to these services instead. A smart DNS proxy is a server that monitors any DNS requests sent from your device. DNS requests are a means of looking up which domain names (e.g. “netflix.com”) are associated with which servers. If it detects a DNS request for Netflix, it sends all the browser traffic for that request through the server to an American Netflix server, thereby changing both your IP address and DNS server.
Similar to the US, copyright trolls send threatening letters to torrenters after identifying their IP address. While we’re not legal experts in German law, the consensus of what to do if you receive a letter is also similar to the US: if it doesn’t identify you by name and doesn’t come directly from the police, ignore it and just let the statute of limitations period expire.
Someone turns their computer into a network access point, and gives is a real-enough sounding name (often imitating popular, well-known ones like “T-Mobile” for instance). When you connect, you’re actually connecting through their computer. And they now will gain access to all of the information you used to login, as well as your browsing activity.
