resolving ip addresses to host names.
Posted on 2004-08-12
While monitoring our badndwidth usage through our firewall, we sometimes find an IP address using a huge chunk of bandwidth. We would like to find out who it is, but we use DHCP, and when I "ping -a <ip address>" the address I get back the host name of a computer shut off or nothing at all.
Is there any sure fire way to resolve an IP address to a hostname? What if the computer isn't part of our domain, but is recieving ip addresses from our DHCP server (Windows 2003 server)?
