</div>The hostname <a href="http://www.google.ro" target="_blank">www.google.ro</a> now¹ also resolves to an IPv6 address, and<br>
check_ping has issues with IPv6 dependending on the ping6(1)<br>
implementation used. These issues will hopefully be fixed in the next<br>
release of the Nagios Plugins; until then, "check_ping -4 [...]" should<br>
do the trick.<br>
