I am currently in search for a tool which will help a LIR to maintain its IP addresses - currently everything is listed inside an Excel file, which is, IMHO, a very limited way of maintaining the lists.
Global Crossing uses a complex but powerful home-grown IP database system which, when coupled with an interface for requesting address space, suffices for our needs. The database very cleanly aggregates and de-aggregates blocks on the fly, tracks user information and customer numbers, can prioritize and de-prioritize blocks for assignment, and can report utilization statistics on an as-requested basis. Everything is written in perl. If there is interest, we can publish these tools as freeware/open source for the RIPE LIR community to use. /david *--------------------------------* | Global Crossing API | | Manager, Global IP Addressing | | (703) 627-5800 | | huberman@gblx.net | *--------------------------------*
