We are choosing a system for managing our IP address space. So we are looking for a special free software like IPPlan. So what we have nowadays:

• Ipplan (Beta IPv6 support)
• SolarWinds IP address tracker (IPv6 support unknown )
• IP module of The NOC Project (BTW, take a look of it, seems to be very promising project) (IPv6 support unknown )
• phpIP (Does not support IPv6)
• IP management from RackTables (Does not support IPv6)

Do you know about any other special software, like written above?

But:

• No Wiki
• No DNS
• No DHCP
• No spreadsheet

Software should provide:

• Clear view of available addresses
• Detail listing of all addresses by subnets/search pattern/owners/additional info
• It must support adding additional info like owner of IP, domain-name, contacts, etc
• Multi user support
• Easy interface
• Software has to be specially written for address management.

• Scalability

• Any OS: win, lin, sol, web
