What is DNS and what is it for?Įvery device that is connected to the internet has an IP address, which consists of a set of numbers like 123.56.43.201, but if we had to type those into the address box in our web browser we would find it difficult to remember more than two or three websites.
It is just a change to the internet settings. This is free and requires no software to be installed on your computer or phone. If ads are driving you nuts, block them by switching DNS servers on your computer. Adverts are necessary, but do there have to be so many? Some websites are just advertising hell and they spoil it for the responsible sites that keep the ads to a minimum. Whether you have a Mac, PC or phone, this ad-blocker is free and no app to install.Īdverts on the web are controversial and few people like them, but they do support a lot of websites and services and they make online content free. Clean up web pages and remove ad irritations with a tweak to the computer or phone DNS server settings.
