This default behavior is not moved into the code. I mean, before the change if you do not have the net stanza in the profile file and you just run the CLI, IPv4 and IPv6 will be enabled by default.

Here with the current changes, removing the stanza from the profile file gives a CRITICAL message :

   0.01 CRITICAL  Both IPv4 and IPv6 are disabled.

I feel an else statement is needed in the code to enable IPv4 and IPv6 by default.

Good catch. I had to remove that "default" to make it possible to detect if the option had been actively set or not. It is more complex than I thought.

Now I see what you mean. If the default profile.json does not have any IPv4 or IPv6 enabled, then there will no network enabled. -- In Backend both are enabled if both are disabled.

You will get the same effect if you run

# zonemaster-cli --level INFO --test basic iis.se --no-ipv6 --no-ipv4

Should CLI be helpful in that case?
