As an enterprise network operator I do not have reasonable policy controls
when path selection is performed by the originating host's selection of
source and destination addresses from the system's set of source addresses
and the destination's set of DNS-registered addresses.

DNS as a routing policy specification language seems inappropriate to me.

I can accept some interaction between the host and network infrastructure
in order to determine the best path to use to a multi-address destination
host; however, we still run into the support issues associated with
applying and maintaining several, multi-PA prefixes to tens of thousands
of subnets.
