+## ASUS / AMI BMC without DNS hostname
+
+Some ASUS ASMB8 and similar BMCs return an invalid JNLP when the BMC has no DNS name. Use `EXTRNIP` in `download_endpoint`:
+
+```yaml
+download_endpoint: "Java/jviewer.jnlp?EXTRNIP=<bmc-ip>&JNLPSTR=JViewer"
+```
+
+Replace `<bmc-ip>` with the address clients use to reach the BMC.
