@@ -6,8 +6,8 @@ This client uses the official XML-RPC API instead of the DynDNS API.
 As a result there is no limit on the number of DynDNS records.
 
 It only works if you're using INWX's own nameservers for your zone.
-Also it's required to have a DNS forwarder running on localhost port 53
-(IPv6 is required).
+Also the Quad9 resolver `2620:fe::fe` must be reachable over IPv6 on port 53,
+though this can easily be changed in the code. Configurability is planned.
