What about rewording that to the following?

I don't see a strong reason to change that text. This specification is
about checking domain names, not IP addresses.

As an aside, I must say that I'm tempted to move everything about CNs to
a separate section,

That would be Ok with me.

or to remove it entirely, because I don't think it's
a best current practice for secure authentication.
Personally, I don't think removing it is going to be a service to the community, because this is the current practice, even if it is not the best one.
