It is still a bad idea. Fixing the clients so they work well with multi-homed servers not only works today with mostly IPv4 servers but also works well with dual stack server and IPv6 only servers. You don't have to have artifially low TTLs on the DNS responses. You get sub-second failover on ne

In a number of cases NATs have a problem to access the internal boxes via an external address from inside the NAT. In such cases it is much easier to just access the box from inside with it's internal address and from outside with its external address. Using the two views allows for all sorts of
