Purpose
Inspect the source IP and User-Agent received by the server.
How it works
The socket peer is authoritative; headers such as X-Forwarded-For are reliable only when overwritten by a trusted, restricted reverse proxy.
Input
Enter text, numbers, a file, or a query target as required. Start with the page example to confirm the format, then replace it with your data.
Interpreting output
Confirm output format, units, and status, then compare with the input and target environment; successful formatting does not prove validity.
Limitations and privacy
This tool contacts the DEA server or an external data source; do not submit confidential data.
