Hi, I've the same issue. I've done the following little patch in my servers.

In the register function, replace :

@socket = UDPSocket.new

by :

    addr_test = IPSocket.getaddress(@host)
    if IPAddr.new(addr_test).ipv6?
       @socket = UDPSocket.new(Socket::AF_INET6)
    elsif IPAddr.new(addr_test).ipv4?
       @socket = UDPSocket.new(Socket::AF_INET)
    end

It work with ipv6, ipv4, hostname with IPv6 and/or IPv4 resolution.
