DNS (Domain Name System) is the part of the Internet protocol stack that translates addresses into IP addresses. This allows a device to access the Internet.

When you're on the internet, you're actually on a network of computers, and not on the direct connection between you and the website you want to visit. The website can only see your IP address, not your actual location.

This is the problem: websites and services can block access to certain countries or regions because of DNS changes. The easiest way to get around this is to use a VPN (Virtual Private Network), but they have their own problems and can be blocked by the websites you're trying to visit.

This is where OLLO DNS VPN comes in. It lets you change your DNS without affecting your IP. This means you can visit websites and services that are blocked in your region, country, or region.
