Your Online Activity Could Be Watched
Due to a particular and stubborn flaw with the Domain Name System (DNS) that translates the complex number
combinations that identify everything on the Internet into easy-to-use names, it's possible that somebody could easily
be seeing what you're doing online.
"IP Leaking" or "DNS Leaking" is a persistent problem that may be too big to eradicate easily at the highest levels,
but could be prevented locally. Everything that connects to the Internet is assigned a unique number called an "IP address"
and computers use these numbers to find and identify one another online. But humans, who primarily use the Internet,
can't be expected to remember random number strings to check their email or buy things on websites, so the Domain Name
System was created to store the IP addresses of certain computers (ones that opt in) and assign them an easy to
remember name (like privadovpn.com).
Unfortunately, if you use an unsecured DNS server like many ISPs do by default, outside parties like hackers, your DNS
provider, or even your ISP can watch what you do online and even keep records of it.
