What Is A DNS Leak?

Domain Name Service is an address book for the internet that is a reference for looking up the addresses you want to visit. DNS security plays a crucial role in making your activities private. A DNS leak means that your DNS queries reach the ISP instead of the VPN server.

How Does A DNS Leak Impact You?

Whenever you request to open a website, the request travels to the ISP who uses its DNS server to look up the correct IP address for that URL. The ISP can effectively see every activity that you do online. A DNS leak occurs when the DNS queries travel outside the encrypted VPN tunnel, allowing the ISP from noticing your web activity. It also allows malicious users on rogue networks to intercept the communication.

What Is a Root Server, TLD Server, And Authoritative Server?

Root, Top Level Domain, and Authoritative are nameservers that hold part of the information about all websites on the internet. The DNS resolver first contacts the root server for information about the website’s address, which then points the resolver to TLD and Authoritative servers for the remaining information, such as the extension (.com, .net, .org) of the domain.
