From an IP address, can I tell what OS is running ?
Case in point, AT&T DNS server IP addresses - do they have a virus ?
Thanks, Duaine
You can't tell from the value of the IP address itself, but you can attempt OS detection by running
nmap -O IP.ad.dr.ess
as root in a terminal window. That, however, won't tell you anything about whether they have a virus.

So, is this windows or unix/linux ?
linux-z6iz:/home/dahechler # nmap -O 68.94.156.1
Starting Nmap 5.00 ( http://nmap.org ) at 2011-08-23 20:11 CDT Interesting ports on dnsr1.sbcglobal.net http://dnsr1.sbcglobal.net (68.94.156.1): Not shown: 999 filtered ports PORT STATE SERVICE 53/tcp open domain Warning: OSScan results may be unreliable because we could not find at least 1 open and 1 closed port Device type: switch *Running: HP embedded OS details: HP 4000M ProCurve switch (J4121A)*

It's probably a favor of Linux. It's HP embedded, the os they use on their switch.
