Does the rockermq-client-python support IPv6?

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?

No files or tests are named in the report. Start by reproducing the RocketMQ v4.9.3 connection with rocketmq-client-python 2.0.0 over IPv6 while comparing the working IPv4 path, then trace where the “No route info of this topic” error is produced. Done means the IPv6 compatibility status is established and any required client changes are covered by a reproducible test.
