[Rails problem]create IP address range?

Is there any way to create IP address range? like 192.168.0.1/24.
It's too annoy to create a data each time.
I find a Rubygems' ipaddress.
http://rubygems.org/gems/ipaddress.
I would like to take this to created IP range.

in new.heml.erb

<%= f.lable :iprange %>
<%= f.text.field :iprange %>

I don't how do used it in the rails' models

ip = IPAddress("192.168.0.1/24")
ip.each do |i|
p i.to_s
end

Somebody can give me some guide.

Are you saying you do not know how to access the value from the text
field? It should be available in the controller in params.
