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.
