How to get a list of IPs for a remote computer in Ruby

I have a app that needs to connect over a socket to a remote computer that now has multiple IP addresses. Is there a way to turn the remote Hostname or IP a list of all the IPs that the system has?

Possibly (Hostname | Ip) => (RemoteMAC) => IPs?

require 'resolv-replace'
Resolv::DNS.new.each_address("oreilly.com") { |addr| puts addr }

produces:

208.201.239.101
208.201.239.100
