If your DNS is hosted by TornevallNET and need to point out a specific amount of nameservers, this is the page you should look at.
Primary Servers
Recursive DNS servers (Use for anyone)
DNS-Servers marked with PARTIALLY RECURSIVE is, as said, "partially" recursive (allows requests from "anyone"). By means, chosen networks - mostly located in Sweden - are allowed to use them as they normally use servers like 8.8.8.8, 8.8.4.4, 1.1.1.1, etc. By chosen networks Telia, Tele2, Bredbandbolaget, parts of OVPN.COM, etc etc, are allowed.
If you feel the resolvers is failing in such cases for you, take a look at the permission list at https://auth.tornevall.net/dns-recursion.txt and/or contact support@tornevall.net if you wish to update something. This permission list shows you which networks that is normally allowed to do recursive requests.
There are more servers like below, that allows recursion but those are the publicly maintained list. Tornevall.org has a bigger backup if it will be necessary (see the bottom of this page).
