Yuck.  We use DNS exclusively.  We register two names for the hosts -
one on the front-side network and one for the backup network.  For those
cases where the server doesn't have backup network interface but is
expected to have one soon, we'll add a CNAME entry for the backup
network DNS entry to point to the front side, but in general we don't
like doing that.  DNS and the appropriately configured routing tables
are all we need.

This works like a charm and the right thing happens.
