NAME

DNS-find-free -- an example tool to help find free spots in your DNS table

DESCRIPTION

This is a tool to help find some unallocated DNS addresses in your files. There are two methods of operation: either by specifying the kind of unallocated space you would like to find, or to employ a script files that specifies this information. Currently the only format of the script file is the SWIP format. In addition, if a SWIP file is employed, an ARIN End User IP Request report can be generated from a template. The report, with some editing, can be sent to ARIN afterwards.
