In Apache you can use the directive LogFormat which allows you to determine what information is included in the header of each log. You create LogFormat strings in the apache2.conf, then use those strings when you use the CustomLog directive.

Example used in the Apache help:

LogFormat "%h %l %u %t \"%r\" %>s %b" common
CustomLog "logs/access_log" common

This means that the logs in access_log will have this information included:

• Remote Host Name
• Remote logname
• Remote User
• Time
• First line of request (put in quotes)
• Final status
• Size of the request in bytes

In the log formats documentation there is a %A - Local IP-address

I have never tested it, but it might work for what you need.
