What generates the ICE candidates on a local webRTC application with no STUN server specified?

I wish to understand what generates the ICE candidates in a local webRTC application that does not use a STUN server.

Without a STUN server configured, the only candidates you might get from onicecandidate are host candidates, based on your system's IP address in its local network. The browser running on your system already knows this IP, and does not need ask a STUN server for it.

A STUN server is only needed to learn what IP addresses a system might be contactable on from outside a NAT. A STUN server acts as a mirror that sends back the IP it sees from packets sent through the NAT.
