# mod_log_ipmask for Apache 2.4
|
|
|
|
This Apache module allows you to mask parts of the client's IP address before
|
|
it is written to log files like the `AccessLog` or `CustomLog`. The `%a` and
|
|
`%h` placeholders provided by `mod_log_config` can be amended, so for
|
|
example `%{16}a` will only use the first 16 bits (two octets) of the remote IP
|
|
address.
|
|
|
|
Masking IP addresses in part or entirely is required by Germany's Telemedia
|
|
Act. Keeping only partially masked IP addresses in logfiles still allows you
|
|
to perform web analytics without having to process personal data.
|
|
|
|
*This module was originally funded and developed by Saxonia's data protection
|
|
officer. Please see https://www.saechsdsb.de/ipmask for details or installation
|
|
instructions (German only) and the source code for original copyright and
|
|

**Caution** This is a fork of the original module, created by

|
|
|
|
Changes against the original version:
|
|
|
|
* Minimal change required to make this module work with Apache 2.4.
|
|
* Removed the enforced masking of the last octet. By default, it will
|
|
still be masked, but you can configure your log format with `%{32}h`
|
|
to get full IP addresses if you wish.
