Hi, expert, I am looking for nmap user mailing list, however I didn't find one. So I am sending email to this list. If it is wrong, please let me know the correct nmap user mailing list. When I run the the command "nmap -sn x.x.x.x/30" to get some of hosts and also their domain name (host name), I found out that wrong domain name is returned: Starting Nmap 5.51 ( http://nmap.org ) at 2012-05-08 15:03 Eastern Daylight Time Nmap scan report for name1.fiberlink.local (x.x.7.28) Host is up (0.00s latency). Nmap scan report for name2.xx.xx (x.x.7.29) Host is up. Nmap scan report for name3.xx.xx (x.x.7.30) Host is up (0.00s latency). Nmap scan report for name4.xx.xx (x.x.7.31) Host is up (0.00s latency). Nmap done: 4 IP addresses (4 hosts up) scanned in 0.72 seconds My ip address is x.x.7,.29, however the host name for that ip address is not my host name. My host name appears for ip address x.x.7.28 which is my old IP address. I am connecting through the Cisco VPN, I connected to my current ip address x.x.7.29 probably half an hour ago, just wonder why the DNS resolution is still wrong. I did some search on internet and didn't find a good answer on this. It would be appreciated that someone shed some lights on this.
