Masking IP-Addresses on logging?

[ts77]

Hey there,

some of you might know that storing full ip addresses in germany is getting more tricky every day and considered a legal problem.
Is there any way to store masked ip addresses in access logs with nginx while retaining the possibility to use web analytics software? 

thanks,

thomas
