CLI tool#
The netaddr package includes a netaddr CLI application.
Note
The tool is meant to be used by humans. Its interface should not be considered stable. Exercise caution when using it in any kind of programmatic context (read: scripting).
If you want a stable interface use the programmatic API.

Interactive shell#
Calling netaddr without any arguments will launch an interactive shell.
The shell uses IPython if available or the built-in Python REPL otherwise. The IPython REPL has more features and offers nicer experience overall.
The shell comes with all parts of the netaddr API pre-imported so you can interact with it right away, with minimal friction:
