If you use the "manual" authenticator plugin on your own laptop, the IP address logged by the CA would be the one your ISP gave you, rather than that of the public server. In addition to the minimal information necessary to create certificates Certbot may also transmit additional information to facilitate reliable operation and debugging of ACME client and server software.
