IPv6Planner - a basic IPv6 subnet planning tool

There are so many ways to create IPv6 Subnet plans. As discussed in IPv6 Buzz 180, an address plan is one of, if not the first step. Because getting started in the IPv6 subnet planning can be somewhat daunting, I wrote this go application to help bootstrap the process. This open source tool can be used along with the web version of ipv6utils, or the CLI tool. It’s not the Swiss army knife, but it’s enough to build a starting point.
