Which ip did ipaddr get?

[myifeng]

ipaddr=172.18.32.149

But 172.18.32.149 is not my ip address, why is this?

hi. we need more context Where is this ip observed?

[zmstone]

If this is from the logs. Likely because emqx (old version?) tried to resolve configured host name fqdn to ip address

I am using emqx in the k8s cluster,I see in my my-mqtt-auth logs that the ipaddr parameter is not as expected.
