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. It currently supports:

• Generating IPv6 address plans from a base subnet
• Supports multiple Points of Presence (POPs)
• Creates hierarchical subnet levels within each POP
• Calculates and displays available subnet counts at each level
• Multiple output formats (text, JSON, HTML)
• Interactive mode for guided input
• Comprehensive help system

Example output:

This tool is not intended to provide a comprehensive address plan.
It should be used to generate a top level heirarchy of IPv6 address plans.
