What Is My IP Address?

Your public IP address as seen by fast.id — also handy for checking a server's outgoing IP.

Command Line Interface

The same data is available as plain text — perfect for scripts, and for checking which IP your server uses for outgoing traffic (e.g. with asymmetric routing).

$ curl ip.fast.id# your public IP, plain text

$ curl ip.fast.id/all# all connection details

$ curl ip.fast.id/json# JSON output

Your IP is only echoed back to you — it is never stored.
