Unusual log entries

[hyperact]

I just noticed the following in my logs:

/?80.145.116.39
/?218.8.94.86
/?66.241.84.168

None of those are my site IP address. These are all coming in through the root folder. Anyone know what this is?

What worries me is that I also see the same entries in my cgi-bin folder, attached to a custom cgi I run, like this:

/cgi-bin/customCgi.pl?80.145.116.39

The cgi does not take a parameter (it just runs a little clean-up routine on my site), so nothing bad happens. But it concerns me that someone might know what is in my cgi-bin folder in order to call it this way; this is a private cgi I use only myself and there is no link to it on my site. How would anyone else know about it? And what ARE those addresses in there?
