I'm not sure what you are talking about, but if you are looking for an unassigned IP address on a network, you have to use a tool like nmap to scan the network for open IPs from a machine already on the net.

I assume that you are on a network with a DHCP server and you are wondering why you are not getting an IP address assigned to you.

Have you (with root privlages at a shell) tried to type: ifup ?

If so, what happened? What is the output of : ifconfig ?

Has your system gotten and IP address in the past?

If so, what OS were you using then?

We need info if we're to help.

i just want to know, how many ip address on the network which is still unassigned? then, why i am not getting a ip assigned to me since i am in the network. my os is RH8.
previously it had not given any ip.

[root@syweb root]# ifup
Usage: ifup <device name>

I think the command you'll need is this:

ifup eth0

(that's a number zero)
