Domain Name System or the DNS is a system that converts your IP address into URLs with common domain names and vice versa. As such, you won’t have to note or memorize your IP address whenever you visit a website.
As you browse the internet, your operating system works by sending a DNS request to fetch an IP address related to the domain. Your internet service provider can log the requested DNS from your operating system and give out your browsing history.
If you have a VPN, any DNS request will come from your VPN provider and not your server thus securing your online operations. Whenever the information comes from a personal DNS server, it means there is a DNS leak. In such a case, your IP address, location and browsing history is no longer safe.
