Federal mandates require IPv6 to the desktop this year (2014). Lack of true IPv6 IPAM may delay our deployment.
The current IPv6 support is only for manual entry of address - IPAM as spreadsheet.
Since IPv6 standard recommended subnet size is /64 (the size of the entire IPv4 internet, squared), it would literally take years to scan a single subnet, even if you scan 1000 addresses per second. We have over 100 subnets at several locations.
So we need the ability to pull IPv6 Neighbor caches from all Cisco routers on IOS and NX-OS and ASA firewalls.
