Only your use of the tool, I suspect.

Yes - most likely, you used ping rather than ping -n.  Without -n,
ping, like a bunch of other tools, tries to resolve addresses to names
for human consumption.

This is because, when you do that, ping's attempt to resolve the
address to a name fails fast, instead of taking a long time to fail.

You don't say what nameserver address(es) you have in resolv.conf, but
I would guess that either your host can't reach it/them, it/they
isn't/aren't willing to provide nameservice to your host, or its/their
nameserver(s) do(es)n't itself/themselves have the ability to perform
reverse lookups (for whatever reason).

The cause is probably also the same, though without details I can't be
sure.

Again, without details I can't be sure, but I suspect this is because
you've got it configured to either talk to a working nameserver or such
that the lookup attempts fail fast.
