Hello, As discussed last month on this list, Global Crossing uses a powerful suite of tools, called IPdb, to manage its address space, address space assignments, and RIR requirements for both IPv4 and IPv6. Version 1.0 of FreeIPdb will be released next week as open source. I will post all the pertinent details in the coming days. /david *--------------------------------* | Global Crossing API | | Manager, Global IP Addressing | | (703) 627-5800 | | huberman@gblx.net | *--------------------------------*
