Address Management for IPv6

Software to help with IP address management (IPAM) has long been available for IPv4, and now IPv6 versions are becoming available. IPAM tools are important in IPv6 as networks have larger address pools, different subnetting techniques, and more complex 128-bit hexadecimal numbers. Here are links to some open source and commercial IPAM packages. IPv6Now does not guarantee any of these packages, links are supplied for information purposes only.

Note this important article from ERNW on security aspects of some commercial IPAM packages: Evaluation of (Security-related) IPv6 Capabilities of Commercial IPAM Solutions.
