[ipv6-wg] tools for ipv6 allocations

Hello everyone, it has been a little bit quiet on this list so i thought i break the silence.. has anyone experiences with commercial tools for ipv6 allocations ? (i mean in this case for a LIR that keeps its ipv6 number bookkeeping) or have you used your own written tools please let me know what you have been using if it is not a good idea to put this issue on the list then please answer me directly (without a copy on the list). Thanks in advance.. (and sorry if this is list-misusing).. Rgds, Raymond
