netaddr

A Ruby library for performing calculations on IPv4 and IPv6 subnets. There is also limited support for EUI addresses.

Version 1.x

The original netaddr which I created in 2007. My use case then was creating an internal IPAM system for Rackspace.

Version 2.x

A complete rewrite and totally incompatible with 1.x. My main motivation now is to reduce bug reports resulting from the poor code quality of 1.x.

Building

To run unit tests, execute the following from the top level directory

ruby test/run_all.rb

To build the gem, execute the following from the top level directory

gem build netaddr.gemspec

Examples

Example code may be found in test/example.rb. This example code runs as part of the unit tests.

Coding Style

I use the following conventions:

  • I use tabs for indention since tabs make it really easy to adjust indention widths on the fly.
  • I do not follow rigid limits on line lengths. My editor auto-wraps so I add a line break where it feels appropriate.
  • I'm not a fan of obfuscation. I prefer clear code over fancy code.
You can’t perform that action at this time.
