Does the rockermq-client-python support IPv6?

[Jasongsq]

My rocketMQ install rocketmq v4.9.3, when I used rocketmq-client-python-2.0.0, SDK throw error like this "No route info of this topic xxx,error:"-1"", My topic name is correct and is exist in blocker。 When I access RocketMQ in an IPv4 network, there are no issues and I can send and consume messages normally. However, when connecting to RocketMQ in an IPv6 network, the above error occurs. Is this because the rockermq-client-python does not support IPv6? If I want to connect to RocketMQ over IPv6, what improvements are needed?

FYI:

rocketmq-client-cpp/src/transport/TcpTransport.cpp

Lines 146 to 177 in c7777af

	TcpConnectStatus TcpTransport::connect(const string& strServerURL, int timeoutMillis) {
	string hostname;
	short port;
	LOG_DEBUG("connect to [%s].", strServerURL.c_str());
	if (!UtilAll::SplitURL(strServerURL, hostname, port)) {
	LOG_INFO("connect to [%s] failed, Invalid url.", strServerURL.c_str());
	return TCP_CONNECT_STATUS_FAILED;
	}
	{
	std::lock_guard<std::mutex> lock(m_eventLock);
	struct sockaddr_in sin;
	memset(&sin, 0, sizeof(sin));
	sin.sin_family = AF_INET;
	try {
	sin.sin_addr.s_addr = getInetAddr(hostname);
	} catch (const MQClientException& e) {
	LOG_INFO("connect to %s failed, %s", strServerURL.c_str(), e.what());
	setTcpConnectStatus(TCP_CONNECT_STATUS_FAILED);
	return TCP_CONNECT_STATUS_FAILED;
	}
	sin.sin_port = htons(port);
	m_event.reset(EventLoop::GetDefaultEventLoop()->createBufferEvent(-1, BEV_OPT_CLOSE_ON_FREE | BEV_OPT_THREADSAFE,
	m_enableSsl, m_sslPropertyFile));
	m_event->setCallback(readNextMessageIntCallback, nullptr, eventCallback, shared_from_this());
	m_event->setWatermark(EV_READ, 4, 0);
	m_event->enable(EV_READ | EV_WRITE);
	setTcpConnectStatus(TCP_CONNECT_STATUS_WAIT);
	if (m_event->connect((struct sockaddr*)&sin, sizeof(sin)) < 0) {

It seems the TcpTransport::connect method is not compatible with IPv6.
