No, unless the developer likes pain, the resolution is the job of the os.
If your box opens a connection to a remote server then the remote server only
sees the ip address of your box. The only way to get a hostname for that ip
address is to look up the ptr record of that ip from the authoritative dns
server responsible for the address space that contains the ip address of your
box.
I think there are exceptions, for example in email. Look, from one of
mine:
Received: from nimrodel.valinor (88.*.*.*) by ctsmtpout2.frontal.correo
(7.2.056.6) (authenticated as ***)
id *** for [email protected]; Thu, 17 Jan 2008 16:29:13 +0100
The smtp server of my ISP logs that my machine names itself as
nimrodel.valinor, and then logs the real IP
:-)
