Justin, Good point. That’s what I am wondering is why is it listening on an IPv6 address. I will check on that.
Thank you.

I'm not sure why it would do that. To be clear, org.apache.activemq.artemis.spi.core.protocol.RemotingConnection#getRemoteAddress is basically just a wrapper around io.netty.channel.Channel#remoteAddress [1] so the exact behavior here will be determined by Netty. It may be worth reaching out to the Netty community for insight. Is the client connecting via IPv6? Is the relevant acceptor listening on an IPv6 address?
