Overview

The public interface is the network interface the standalone server node (or domain server nodes) use to receive business payload.

WildFly Networking Concepts - Public Interface

The interface is declared in standalone.xml as:

<interfaces>
    ...
    <interface name="public">
         <inet-address value="${jboss.bind.address:127.0.0.1}"/>
    </interface>
</interfaces>

or in domain.xml as:

<interfaces>
    ...
    <interface name="public"/>
    ...
</interfaces>

In the case of domain mode, the actual specifics are host dependent, so that is why the address is declared in a host-dependent manner.
