+---
+The UDP client module sends messages to a the configured `host` and `port`. This module does not receive any message and so using it as an `input` to a [route](/concepts/routes) would be pointless.
+
+- **type**: `net.udp.client`
+- **params**:
+    - **host**: IP or FQDN to send message to
+    - **port**: UDP port to send messages to
+
+### Example
+setup up a UDP client that will send UDP packets to `127.0.0.1` on port 8888
