This came from my raw log files: Test/0.1+libwww-perl/5.53 Seen this pop up a few times @ 18.104.22.168, just wondered if possibly a competitor is downloading, or someone running a test? Why does it show the path /test in the log files
IP addresses are four octet (byte) numbers that uniquely identify machines on the Internet, usually represented in decimal with octets separated by periods. For example, 192.168.12.1. A class C is where the first three bytes are the same. Since IP addresses are allocated in groups, one of the most common groups is to allocate 256 IP addresses together. Thus 192.168.12.anything would be a class C. So what he is saying is that all the addresses in this block of address are allocated for DSL connections to the Internet.
In this case, it was probably someone on their own DSL connection running some tool or spider they had written or acquired from somewhere.
