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 opensuse@opensuse.org; 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
The only rub here is is that my IP is fixed and the ISP manually creates the reverse lookup and adds that to it's reverse zone. In my case they added mail.3111skyline.com as the reverse lookup for the IP 66.76.63.120. Which is fine, but I couldn't explain why all outbound ssh sessions show up as mail.3111skyline.com. Now I know, this thread and the input has lifted the veil of confusion. -- David C. Rankin, J.D., P.E.
