+## ⚠️⚠️⚠️ Note regarding hosted version at `ddns.pboehm.de`
+
+The hosted `ddns` service with custom hosts under the `d.pboehm.de` domain (e.g `test.d.pboehm.de`) is not available
+anymore! I did not use this service for quite some time and recently there were some issues which resulted in downtime
+and expiration of all registered hosts.
