If we define a network as something, which consists of: clients and
servers (hosts) - then the problem on hosts could be solved with DNS as
above.
Clients could be either:
1. NATed behind a HSRPish device so that they always use the same IP,
   and the NAT device translates to whichever uplink is currently active
or
2. Reconfigured if one link should be down
