why fsockopen() use root dns info?? - about php


I have poor english.. sorry..

my office is using private ip(192.168.x.x) and setting dns server.
i hope use web mail at office, i am programming..
----------------------------------------------------
$fp = fsockopen("off.com", 110, $errno, $errstr, 30);
if(!$fp){
echo "$errstr ($errno)";
else{
echo "result : ".$fp;
}

result : connection refused (61)
-----------------------------------------------------
i checked system.
and found problem..
problem is that fsockopen() used root dns info.(connect real domain, off.com)
not used office dns info.

office dns server------------
off.com - 192.168.123.107
