[ppml] IP Address Management Tools

Hello all,
Changing my status from a lurker to a participant on this list, I would
like to inject that we developed such a system in-house which manages
all aspects of IP address management, as well.  This system handles
provisioning/deprovisioning of IP networks for customers and internal
usage, reports usage by type of service, provides utilization statistics
per service/subnet/customer, handles automatic updating of SWIP, network
architecture information (ASNs, VLAN IDs, assigned routers, etc.), and
many other aspects of IP management.

The system was built almost entirely based upon the ARIN requirements
for requesting new IP address space.  As the ARIN requirements became
somewhat clearer, the means by which to gather and store the data became
much harder to deal with.  A team of three very talented in-house
programmers designed the system for us and it took them about a month or
so to complete.

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

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.
probably means a Java framework combined with Python for scripting glue.


Some things which are definitely not appropriate are MySQL and PERL.
are already several hack jobs that people have thrown together using
and MySQL but they don't do the job well enough, would never be adopted
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
integrate into their larger systems.
