apache log file question: changing ip's

[Joel Hammer]

Just looking at hits in my access.log for those wedding pictures.
Some numbers (ip's) seem to change for every requested document, even when
the requests are sequential and less than a second apart.
For example:

152.163.252.71 - - [02/Jun/2003:16:55:11 -0400] "GET /Ellen/styles.css HTTP/1.0" 200 1328
152.163.252.69 - - [02/Jun/2003:16:55:11 -0400] "GET /Ellen/thumbs/1Bouquet1.jpg HTTP/1.0" 200 4561
152.163.253.34 - - [02/Jun/2003:16:55:11 -0400] "GET /Ellen/thumbs/1Bouquet2.jpg HTTP/1.0" 200 4876
152.163.252.164 - - [02/Jun/2003:16:55:12 -0400] "GET /Ellen/thumbs/1Maeli.jpg HTTP/1.0" 200 4098
152.163.253.65 - - [02/Jun/2003:16:55:12 -0400] "GET /Ellen/thumbs/1Maeli2.jpg HTTP/1.0" 200 4966

Obviously, this is one person logging on and getting the thumbnails from the
index page. So, what is this constant change of ip's? Is the some security
feature of aol?

This makes keeping count of how many people visit the web page difficult!

Thanks,

Joel
