      Resolve the hostname to IP addresses, and find one reachable address.

      • recreateSocketAddresses

        public void recreateSocketAddresses()
        Performs a DNS lookup of hostname and (re)creates the this.addr and this.electionAddr InetSocketAddress objects as appropriate If the DNS lookup fails, this.addr and electionAddr remain unmodified, unless they were never set. If this.addr is null, then it is set with an unresolved InetSocketAddress object. this.electionAddr is handled similarly.

      • getReachableAddress

        public java.net.InetAddress getReachableAddress​(java.lang.String hostname,
                                                int timeout)
                                         throws java.net.UnknownHostException
        Resolve the hostname to IP addresses, and find one reachable address.
        Parameters:
        hostname - the name of the host
        timeout - the time, in milliseconds, before InetAddress.isReachable(int) aborts
        Returns:
        a reachable IP address. If no such IP address can be found, just return the first IP address of the hostname.
        Throws:
        java.net.UnknownHostException
