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.

This is the number of address blocks to find. The block size is whatever your DNS table happens to use.

--swip-input FILE
