Setting address of whois service for ruby whois gem - ruby

Question

Using the ruby whois gem, how do I set the server address of the whois service?
Setting the bind_host, I get an error.
> whois_client = Whois::Client.new(bind_host: "192.0.47.59", bind_port: 43)
=> #<Whois::Client:0x00000008188e7e50 #timeout=10, #settings={:bind_host=>"192.0.47.59", :bind_port=>43}>
> record = whois_client.lookup('wandajackson.com')
Whois::ConnectionError: Errno::EADDRNOTAVAIL: Can't assign requested address - bind(2) for "192.0.47.59" port 43

I'm pretty sure bind_host doesn't refer to the host used for the whois lookup, but instead refers to the adapter binding on the server running your code. By default it binds to 0.0.0.0, or all the adapters on the local server.
If you want to have the whois gem use a custom server address for looking up whois information then it appears that you have to specify it in one of the following ways:
# Define a server for the .com TLD
Whois::Server.define :tld, "com", "your.whois.server.address"
Whois.whois("google.com")
# Define a new server for an range of IPv4 addresses
Whois::Server.define :ipv4, "10.0.0.0/8", "your.whois.server.address"
Whois.whois("10.0.0.1")
# Define a new server for an range of IPv6 addresses
Whois::Server.define :ipv6, "2001:2000::/19", "your.whois.server.address"
Whois.whois("2001:2000:85a3:0000:0000:8a2e:0370:7334")
