All About DNS
Domain Name System(DNS) is very similar to the phone directory, but of internet. Instead of phone numbers, IP addresses are used for communication between two computers. An example of IP address : 192.168.1.1. But remembering all these numbers for all the sites on the internet is a messy task for humans and almost impossible to remember. You would need an excellent memory and a great deal of patience as well.
However, DNS solves this issue by giving a computer a name that is perceivable by humans and convert it internally into IP address. A DNS server allows you to visit various sites on the internet. Your default DNS server would be your Internet Service Provider’s DNS server. So although all information is not recorded by your ISP at least the sites which you are visiting can be seen and can be logged by your ISP.

What Does DNS Allow An ISP To See Through?
DNS can be compared to a simple mechanism like directory inquiries. An operator asking your information and finding the person’s number you are looking for. You would provide a name for it to find, and it also has other information like:
- Whom to call?
- Time of the request
- Your phone number and your location
In an internet based scenario this turns out to be:
- Type URL
- A request sent to DNS server for asking IP address
- DNS server will find IP and return it back to you.
So your ISP can see that a computer at IP 192.168.1.1 looked up IP for www.vpnshazam.com at 9:40pm on April 24, 2018. This is a lot of information to give. Go through our post on Stay Safe From Cyberstalking to know potential threats caused by information you give.
