check_ping strange behavior with google

[Cosmin Neagu]

Hi nagios users,

Starting from yesterday, check_ping is behaving strange for a single host.
When giving -H parameter as www.google.ro it gives CRITICAL - Network 
Unreachable
But when giving -H parameter as IP address it is working. I have checked 
and there are no DNS issues


nagios at mon2:/usr/local/nagios/libexec$ ./check_ping -H 173.194.35.159 -w 
3000.0,80% -c 5000.0,100%
PING OK - Packet loss = 0%, RTA = 46.97

nagios at mon2:/usr/local/nagios/libexec$ ./check_ping -H www.google.ro -w 
3000.0,80% -c 5000.0,100%
CRITICAL - Network Unreachable (www.google.ro)
nagios at mon2:/usr/local/nagios/libexec$ ping www.google.ro

After a little more search
Other sites works ok when used with check_ping, but not site containing 
goole is working

nagios at mon2:/usr/local/nagios/libexec$ ./check_ping -H www.google.de -w 
3000.0,80% -c 5000.0,100%
CRITICAL - Network Unreachable (www.google.de)
nagios at mon2:/usr/local/nagios/libexec$ ./check_ping -H www.google.com -w 
3000.0,80% -c 5000.0,100%
CRITICAL - Network Unreachable (www.google.com)
nagios at mon2:/usr/local/nagios/libexec$ ./check_ping -H www.google.it -w 
3000.0,80% -c 5000.0,100%
CRITICAL - Network Unreachable (www.google.it)

Any idea why?
