One’s browsing activities can be tracked and used by internet service providers as well as different companies by logging the queries of DNS servers. Because just about all DNS servers keep logs, meaning that they store DNS requests received for a period. Thus, someone could take a look at the DNS log records and find out your browsing habits and history. Yes, this is possible!

What can your ISP really see?

This is dependent on a couple of factors – the IP address that is automatically assigned to you by the ISP when you take up the service and the kind of information you readily share online. Let’s say, for example, you are one of those extremely careful people who does not put any of their confidential information online (granted, this is very difficult to do nowadays). In this case, the most common data that your ISP will gather, based solely on your active IP address, includes the following:

  • How much time you spend on certain web pages
  • The URLs you visit online
  • Your online/offline habits (when you typically log in and off)
  • How much time you spend on certain web pages

Why Do I need to use no log DNS and why DNS encryption matters?

DNS is a public directory and your ISP sees almost every single request made to it. Because these DNS queries are never encrypted and are public, your ISP or a third party will see every query sent from your computer, even if you are using an encrypted connection.

If you are using your ISP’s service to read your emails, do online research, watch videos, make purchases, use apps, and almost anything else online, then your ISP has a record of where you go and what you do.
