The term 'caching DNS' doesn't actually mean anything.[1] All DNS software
_caches_; even the stub resolver in glibc caches. I spoke of something
different and quite specific: a local recursive resolver.

And what I was saying is: You should run one on modern networked *ix
machine generally. Because it's 2016.

Even DHCP-client hosts can have local recursive resolvers. This is
useful:

or

If you cannot reach _127.0.0.1_ because 'your network settings were
wrong during boot', you have somehow managed to achieve such an epic
degree of TCP/IP failure that I'm not sure you should be running *ix
machines. ;->

Fortunately, I don't think that's even possible.
