Ohai plugin to return semantic reference attributes for network addresses

gistfile1.rb

# This might not work on newer (than 0.10.6) versions of Chef.
# Thanks for pointing to my new gist, spkane :)
# https://gist.github.com/1040543

require 'rubygems'
require 'ohai'

o = Ohai::System.new()
o.all_plugins

# And retrieve some useful semantic reference attributes for network interfaces
o['network']['interfaces'].each do |iface, addrs|
  
  addrs['addresses'].each do |ip, params|
    o["ipaddress_#{iface}"] = ip if params['family'].eql?('inet')
    o["ipaddress6_#{iface}"] = ip if params['family'].eql?('inet6')
    o["macaddress_#{iface}"] = ip if params['family'].eql?('lladdr')
  end
  
end

Just in case you stumble on this as I did, there is a more updated version of this that works in Chef 10.6 here:
