[https://www.opennic.org/ OpenNIC] provides free uncensored nameservers located in multiple countries. The full list of public servers is available at [https://servers.opennic.org/ servers.opennic.org] and a shortlist of nearest nameservers for optimal performance is generated on their [https://www.opennic.org/ home page].

To retrieve a list of nearest nameservers, an [https://wiki.opennic.org/api/geoip API] is also available and returns, based on the [https://wiki.opennic.org/api/geoip#url_parameters URL parameters] provided, a list of nameservers in the desired format. For example to get the 200 nearest IPv4 servers, one can use https://api.opennicproject.org/geoip/?list&ipv=4&res=200&adm=0&bl&wl.

Alternatively, the anycast servers below can be used; while reliable their latency [https://wiki.opennic.org/opennic/dont_anycast fluctuates a lot].

 169.239.202.202
