Unexpected behavor: Creating Log Directories

[Werezwolf]

$_DIR['ROOT'] = $_SERVER['DOCUMENT_ROOT'] .'/..';//Outside the scope of WWW root
$_DIR['LOG']  = $_DIR['ROOT'] .'/logs/LogFiles/' . $_SERVER['SERVER_NAME'];
if (!is_dir($_DIR['LOG'])){Mkdir($_DIR['LOG'],0700,TRUE);}

I created a directory to log with on my Dev server assigning all sorts of values to these logs but i got some resolving DNS names that are not associated with my website at all.

 

Why would $_SERVER['SERVER_NAME'] be resolving other names that are not related to my server?

 

Expected Posiblities

 

127.0.0.1

Internal IP Address

External IP Address

test.example.com (My Website URI)
