Well, thats a new one on me too!

but getent output might be easier to parse than host if
you're using it in a script...

(And I suspect it's also a distro thing - host is present on Debian,
as is getent, but who knows for other distros)

If it uses glibc it will have getent. host, dig and other utilities that
are part of a resolver package on the other hand may well not be present.

In truth there is no single utility that you can be certain will always be
available to you so it's useful to be familiar with several. For scripting
I prefer to use perl - that way I know what's available to me regardless
of where it's running.
