Get hostname from IP address on internal network
I am a lowly Systems Tech at a company and I am assigning IP addresses to laptops to be added to the domain.
I am trying to give laptop number 33 the private IP 10.3.0.33, but it looks like another computer has that address already.
I have a Fedora 6 machine on the network and I can ping the 10.3.0.33 address, but is there a way that I can pull its hostname to figure out which one it is?

Try "nslookup <ip address>", and it will return a host name. This will only work, though, if that address is in DNS, or is somehow defined.

No, our PC's on the internal network are not defined in the DNS server.

This is a samba command and uses netbios and not dns to get names/IPs. You need samba installed in your system to use it. The correct syntax to get the computer name from the IP is
Code:
nmblookup -A xx.xx.xx.xx
