F. In Section 1.6.1 of the Baseline Requirements, REPLACE the definition for "Reserved IP Address" with the following: An IPv4 or IPv6 address that the IANA has "False" for Globally Reachable in either of the IANA Special-Purpose IP Address Registries:

https://www.iana.org/assignments/iana-ipv4-special-registry/iana-ipv4-special-registry.xhtml or


and the first of those links has marked as ‘false’ for globally reachable.  Now, it’s true that is marked ‘true’ for globally reachable, but I don’t think that anyone should be able to authenticate themselves as controlling that address, so no CA would issue a certificate containing that address.

That’s a brave assumption. RFC6890 describes the block as « Not usable unless by virtue of a more specific reservation » (Section 2.2.2, Table 7). Precisely what RFC7723 and RFC8155 do.
