[env: CLOUDFLARE_ZONE_ID]
--zone-name <NAME>

Talk to all available IP services and check that an absolute majority
of them have the same answer before making any changes. Use this if
you are extra paranoid and don't want a hacked or buggy service to be
able to give you the wrong IP back
This utility supports configuration via command line argument, through ENV
variables, and through .env files. The --help output lists the named
environment variable to use for each option. CLI arguments override ENV
variables, when provided.
