Anonip masks the last bits of IPv4 and IPv6 addresses in log files. That way most of the relevant information is preserved, while the IP address does not match a particular individuum anymore.

Depending on your Web server, the log entries may be piped to Anonip directly or via a FIFO (named pipe). Thus the unmasked IP addresses will never be written to any file.

It's also possible to rewrite existing log files.

Anonip can also be uses as a Python module in your own Python application.
