wiki/services/dns/Recursive-DNS-resolver.md

If you want to run your own recursive DNS server, you must find upstream servers that are authoritative for the dn42 zones.

You may use some servers listed in the [[table of anycast servers|Providing-Anycast-DNS#Persons-providing-anycast-DNS]], or just use `172.22.119.160` and `172.22.119.163` (ns{1,2}.fritz.dn42).
