Fratozzi Posted January 19, 2020 Share Posted January 19, 2020 Hi everyone, I'm trying to get the name of the machine in use. If I use this feature locally, it works. function visitor_machine_name(){ $machine_name = gethostbyaddr($_SERVER['REMOTE_ADDR']); return $machine_name; } But as soon as I try it on an online server I get the DNS name back, like this: mob-3-91-125-82.net.vodafone.it What can I do?

requinix Posted January 19, 2020 Share Posted January 19, 2020 You cannot get the name of the computer. The internet does not work that way. Quote Link to comment https://forums.phpfreaks.com/topic/309902-php-get-machine-name/#findComment-1573643 Share on other sites More sharing options...

Is there no way to get it? For example using JS. That is, how does DropBox, for example, obtain the name of the logged device?

In case using $ _SERVER ["REMOTE_ADDR"]; to get the name of the dns how can I remove all those characters and know only the final part? For example: With that function I get this: mob-3-91-125-82.net.vodafone.it host86-197-dynamic.3-87-r.retail.telecomitalia.it 93-32-55-29.ip32.fastwebnet.it mob-5-90-154-87.net.vodafone.it I would like this instead: net.vodafone.it retail.telecomitalia.it ip32.fastwebnet.it That should be the name of the internet provider I connect to.
