This occurs through the usage of Onion links, or Onion url’s, which end in the .onion suffix These Tor Onion links are different than normal ones in that they can only be seen when running the Tor client. In other words, even if you know an Onion url, it does no good unless you are running Tor, as you will just get errors when you try to visit it.
