How To

Using OpenNIC means changing your DNS settings to use one of the many public Tier-2 servers on offer. Changing your DNS settings can seem daunting at first if you have not done it before. After you have changed your DNS settings a few times you will see it is easier then it seemed and soon you’ll be teaching others! To help you ease into your DNS settings, there are two rules you must always remember.

  1. Always choose at least two DNS servers (from here)
  2. Ensure the DNS servers are not in the same location or hosted by the same administrator

Following these simple rules, you’ll avoid losing DNS when one server goes down. Luckily we are here to help even more than the two golden rules above. Below we have a list of guides which explain to you how to change your DNS settings on a variety of Operating Systems and appliances.

Note that a number of public servers are marked as “whitelisting”. These servers are not open for general public use, but rather require you to register your IP address with OpenNIC. These servers will have lower traffic and fewer problems with DDoS attacks, allowing for greater reliability. You can find more information about this service on our wiki page.
