Brian,

Thanks for responding:

This code:

require 'rubygems'
require 'netaddr'
ipadd = NetAddr::CIDR.create("192.9.200.0/24")

gives: 

/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`gem_original_require': no such file to load -- netaddr (LoadError)
        from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`require'
        from ci.rb:2

This code:

require 'rubygems'
require 'net_addr'
ipadd = NetAddr::CIDR.create("192.9.200.0/24")

works.

Now, how am I supposed to learn the right string to put into the require
call.  The command to install was:

gem install netaddr


I don't remember why I guessed 'net_addr'
