just an FYI...

We have been working with a Company named Diamond IP Technologies, to
develop such a tool to help us manage all of our private and public IP
space, called NetControl.

Please contact Michael Dooley directly at mdooley at diamondip.com,
610-423-4770 for more information.

I suggest that ARIN should provide such a tool in furtherance of its 
purposes such as numbers 4, 5 and 8. You can read the full text of those 
numbered purposes at this URL: 

I would like to see a discussion of this on the agenda at the next members 

I envisage this tool as something which uses a proper hierarchical data 
model for IP addresse, not a relational data model, and which uses an 
appropriate programming language which could be incorporated into 
commercial software packages or adopted by enterprise IT departments. That 
probably means a Java framework combined with Python for scripting glue. 

Some things which are definitely not appropriate are MySQL and PERL. There 
are already several hack jobs that people have thrown together using PERL 
and MySQL but they don't do the job well enough, would never be adopted by 
enterprise IT departments or commercial network management packages. In 
addition, MySQL is a RELATIONAL database but IP address ranges are 
hierarchical in nature and are better suited to an object-oriented or a 
hierarchical database model. The intention is not to do another hack job 
but to provide a reference implementation that other people will adopt and 
integrate into their larger systems.
