How does Fabric cli get ip of peer/orderer in the example of byfn?

Could any body tell me how the cli knows the IPs of other peers and orders just according to the Host in the configtx.yaml?
When does the DNS information generated?
Can anybody also tell me some more information about the configuration below "CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock"?

          When you run fabric example, it always refer default credentials or already confirugred fabric configuration.



          For example, if you use basic fabric example, you will run [your directory]/fabric-dev-servers/startFabric.sh



          this file refer already configured information. One of them is connection profile. If you look at createPeerAdmin.sh file, you can find DevServer_connection.json. This file contains connection information for the fabric network.



          As you are using byfn.sh, you can add the host ip address using "extra_hosts" in docker-compose.yaml file.



          As there is no definition about this, it will use localhost as default.



          https://medium.com/1950labs/setup-hyperledger-fabric-in-multiple-physical-machines-d8f3710ed9b4



          like this,



          extra_hosts:
          
          - "peer0.org1.example.com:192.168.1.10" 
          
          - "ca.org1.example.com:192.168.1.15"   
          
          - "peer0.org2.example.com:192.168.1.20"
          
          - "ca.org2.example.com:192.168.1.25"

          • I am not able to find startFabric.sh nor DevServer_connection.json in the whole Hyperledger github.com/hyperledger. And I don't know which Fabric example you are talking about neither. Would you please share more information? Especially the information about the byfn sample would be much appreciated.
