No application should ever use IPs (well, I'm sure there are cases, but

Raw, hard-coded IP addresses are useful as a backup to the URL when an application needs to be able to "phone home" from a customer box that doesn't necessarily have DNS access or a host table entry.

And likewise, host table entries are ideal for directly accessing internal servers that aren't directly reachable from outside, at least in organizations that aren't big enough to warrant an internal DNS.
