Please be more specific, which OS does this happen on?
 [2010-06-06 12:32 UTC] hm2k@php.net 
Not Windows. I was testing on CentOS 4 and 5, but based on Google results, I'd say it's more common across many Linux based servers.

Example problematic domains:

dns_get_record('en91.tk', DNS_NS);
dns_get_record('serverdns.ce.ms', DNS_NS);

even if I make an Exception 
this error come !!

the only way to hide is just close the reporting from php.ini :(

using error suppression (@dns_get_record('example.com')) works, even it doesn't solve the problem...
