Quick start

This server shows you exactly what arrives from your device: when, from which address, over which protocol, how big your message was and how many bytes it really took on the network. You can send any payload: text, JSON, binary. Nothing has to follow a specific format.

This is a test environment. Everything you send to this server, including the content and your sender address, is publicly visible. See Privacy.

  2. Send a message from your device to IP address 164.30.75.205, UDP port 41300 or TCP port 12400, unencrypted or encrypted with DTLS or TLS. It appears within about a second.
