How to use getname() ?

I seem to stupid but how can I use getname?!? My aim is getting the domain or subdomain behind an IP-address. I required socket and tried then:

hostname = getname(IP)

but this doesn't work. I also can't get wiser by reading the doc about it: http://www.ruby-doc.org/stdlib/libdoc/resolv/rdoc/classes/R... .

Someone knows how to use getname() ?

Looking at resolv.rb will show you an example. I don't know why that's
not on the Resolv page.

require 'resolv'
hostname = Resolv.getname('127.0.0.1')
