Add an IPSANS to crpto-config.yaml

Fotis Michalopoulos

Hello, i am currently running a 1.4 fabric network with ca server deployed as well.
I am trying to call fabric-ca client from a remote host . 
I understand that i need to add my remote's host IP as an IP Sans in my crypto
config.yaml before CA container gets deployed.
I would like to ask the exact command for adding an IP SANS to crypto.conifig with an example.
After that, do i need to use fabric client with a particular CSR (certificate signining request).

Thanks in advance,
