Forgive me for my non-opperational post ;-) I'm working on a IP management system. It stores the addresses in a MySQL database (could also work with oracle) and a command line interface for allocating IPv4 addresses. Conseptually its like the tree program by Charley Kline. Its written in Java and uses JDBC. If this sounds like something folks might be interested in drop me a note and I'll send you a copy of the source once I get it to beta. Oh, I've got something simular for DNS and am thinking about making them work togther ;-) This software is GPLed, its free. If you are interested in things like these drop me a note and tell me features you would like to have. -Rick =================================================================== Rick H.
