fsockopen problems

hello, I'm having some problems with fsockopen and was hopping for some help. I try to connect to a host via fsockopen and I get "getaddrinfo failed" errors, but if I try fsockopen with google, everything works. sample test code $fp=fsockopen('apps.subname.domain.com/xml_2.4/xml.php',80,$errno, $errstr); var_dump($errno); var_dump($errstr); $fp=fsockopen("000.00.00.000/xml_2.4/xml.php",80,$errno, $errstr); var_dump($errno); var_dump($errstr); $fp=fsockopen('www.google.ca',80,$errno, $errstr); var_dump($errno); var_dump($errstr); (sorry for sanitizing, not my choice.) I can ping the host from the server, and going to this site in a browser gives the expected output.
