Probably an expectation for floating IPs for load balancing instead of DNS.

Relatively simple inside a network range you control but no idea how that works across different networks in geographical redundant setups

Agreed; I have no idea how you'd implement that across multiple ASNs, which is definitely a requirement for multi-cloud or geo-redundant architectures.

Seems like you'd be trying to work against the basic design principles of Internet routing at that point.

    You can configure your assigned network numbers that other AS are allowed to announce certain networks of your own. Not uncommon for in examples authoritative name server addresses.

      TIL, I always thought IP:ASN mappings were 1:1.

        With cloud providers and such the wording could also be "bring your own address".
