*.localdomain != localhost
".localdomain" is not a reserved suffix (or prefix). I'm not aware of any product expecting *.localdomain to resolve to localhost, however I am aware of at least one product that defaults to ".localdomain" as its DNS suffix provided via DHCP (pfSense). This leads to unexpected results when attempting to access a host that's offline (or a host that's online, when nsswitch.conf is [mis-]configured to have myhostname ahead of DNS). Operate on: localhost (and localhost.) *.localhost (and *.localhost.) localhost.localdomain (and localhost.localdomain.) *.localhost.localdomain (and *.localhost.localdomain.) We should not cover: *.localdomain (nor *.localdomain.) localdomain (nor localdomain.)
