We have 3 internal DNS servers, for redundancy purposes.
We always use URL when possible, some 3rd party software does not allow.
Issue is when IPs change (internal or external), procedure to flush DNS
cache, etc. is not always followed to the T.
Another issue is, when running multiple IPs (interfaces) on the I, and
when I is the client or initiates the connection, static routes must be
coded on the I.
These statics can only be IPs.

Changing IPS is never fun, nor smooth.
Too many touch points.

I disagree. If your company changes ISP's, etc then all customer's have
to change. Nope, no hardcoded host table entries or IP addresses. If they
can't justify the time to setup DNS on their IBM i or some other box then
they need to use some external DNS server.

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.
