From 229e8bf2bb1e8367120402f75793a43af7b430cd Mon Sep 17 00:00:00 2001 From: Alan Somers Date: Wed, 21 Aug 2019 14:52:12 +0000 Subject: ping: do reverse DNS lookup of the target address MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When printing replies, ping will now attempt a reverse DNS lookup of the target. That can be suppressed by using the "-n" option. Curiously, ping has always done reverse lookups in certain error paths, but never in the success path.
