When I try to remove the IPv6 address from a host, the smart proxy fails to update the DNS server.

1. The foreman server doesn't set the resource type when sending the delete request for an fqdn to the proxy. It calls <url>/dns/<fqdn> twice instead of <url>/dns/<fqdn>/A and <url>/dns/<fqdn>/AAAA. This causes the proxy to default to A and deleting the A record twice (rather than the A and the AAAA record). I believe this can be fixed by changing the destroy method in ./lib/net/dns/forward_record.rb to

   def destroy
     super
     proxy.delete("#{hostname}/#{type}")
