You’ve found an old host entry that you no longer needed. Whether the old record is now in DNS or should no longer exist puppet makes removing it simple.
host { 'syslog':
ensure => "absent",
}
host { 'ntpserver.example.com':
ensure => "absent",
}Removing puppet managed host entries is as easy as the code snippet illustrates. A simple “ensure => ‘absent’” is all you need.
