We recently added a directory’s IPs to our listings.  The main goal is to identify networks  that host large groups  on the same IP.  From my experience these directories rarely go anywhere.  Most of them end up as PR0 or NA directories.  Many are easily abandoned, since little effort was put into building them.

While cleaning up the article directory category I found many  domains that were parked.  By searching the database for the IPs of the parked domains I was able to find hundreds of other parked domains.  These are directories that escaped the automated dead link check built into the system.  I will continue to remove the parked domains in this manner. In the next while, I will try to concentrate on quality rather than quantity.
