Mac OS X での名前解決についてメモ。
OS X apps may not honor /etc/hosts because they don't necessarily go through
the unix like name resolution path but use the dscache.
dxy-mac:~ dxy$ dscacheutil -q host -a name www.google.com
name: www.l.google.com
alias: www.google.com
ip_address: 66.249.89.99
ip_address: 66.249.89.104
ip_address: 66.249.89.147
dxy-mac:~ dxy$
