note 103728 added to function.gethostbyaddr

If there are several host names for one IP address (many domain names can link to the same physical computer/server), gethostbyaddr() will return a domain name AT RANDOM. I'm surprised it hasn't been said before. You can try and see by yourself. On some shared hosting services, it will not give you any domain name that is registered to that server (fortunately) but a general domain name referring to clusters. Try it on your own server if it is referred by at least 2 domain names, if you have one. ---- Server IP: 69.147.83.197 Probable Submitter: 92.3.228.37 ---- Manual Page -- http://www.php.net/manual/en/function.gethostbyaddr.php Edit -- https://master.php.net/note/edit/103728 Del: integrated -- https://master.php.net/note/delete/103728/integrated Del: useless -- https://master.php.net/note/delete/103728/useless Del: bad code -- https://master.php.net/note/delete/103728/bad+code Del: spam -- https://master.php.net/note/delete/103728/spam Del: non-english -- https://master.php.net/note/delete/103728/non-english Del: in docs -- https://master.php.net/note/delete/103728/in+docs Del: other reasons-- https://master.php.net/note/delete/103728 Reject -- https://master.php.net/note/reject/103728 Search -- https://master.php.net/manage/user-notes.php
