We are in need of a software package to manage our IP space. We've looked at several products on the market but haven't found anything that really suits an ISP's needs very well. Does anyone know of anything on the market that works well? It should understand CIDR and be hierarchical. Most products we've seen have been aimed more at the Enterprise market and include a lot of things we don't need like interfaces to DNS and DHCP. Any suggestions? -- Brandon Ross Network Engineering 404-815-0770 800-719-4664 Director, Network Engineering, MindSpring Ent., Inc. info@mindspring.com ICQ: 2269442 Stop Smurf attacks!
