Who Are You

DNS leak test

Your VPN may carry your traffic while your DNS lookups still go to your own provider, which tells whoever runs the name servers where you really are. This test makes a lookup nobody made before and asks the name server who made it: your resolver, its country and network, compared with the address sites see.
