WARNING: Reverse DNS does not work on this host. If you enable 'TLS', it will not work

When I execute the hopsworks-installer.sh (2.2)，there is a warning message:

WARNING: Reverse DNS does not work on this host. If you enable ‘TLS’, it will not work.
Hostname: aicoremaster
Reverse Hostname: bogon
Azure installation: please continue, we will try and fix this during the installation.
On-premises: you have to configure your networking to make reverse-DNS work correctly.

What is the Reverse DNS? How do I install or configure it？

Someone else can probably provide a more accurate answer and in-depth answer.
But I am pretty sure the Reverse DNS is implemented through
Consul in Hospworks.

I’ve already known the cause of this issue. If the host has already bound a domain name, then the host name should be consistent with the domain name.
