Time and again I am not able to find IP addresses of a certain percenatge of my web site visitors in my Apache raw log files.
For example, a vistor sends me a web form email, and I am not able to find his/her IP address in my log file. Same about some customers, who placed orders from my web site - their IPs simply do not exist i my log file.
Does this mean, there is a problem with the Apache server where my web site is hosted? What are other possible reasons for this?
