DHCP Address Pool

[Guest]

Hi,

I am trying to locate a spare IP address on our domain.
Address pool range is Start IP 192.168.10.1 to End IP 192.168.10.254

We have some ranges excluded from distribution (used for fixed IP)
192.168.10.240 to 192.168.10.254 is excluded from distribution.
How can I find out which IP's in the excluded range have already been
assigned to a device. Pinging the address will not work because some of the
devices attached may may ping disabled.

thanks, PL

If you run DNS and clients are registering, you should be able to look
there. If not, start assigning IP addresses. Windows will tell you if
there's a conflict. Then, since your DHCP scope is a single contiguous
block, change it to 192.168.10.1 - 192.168.10.239 and forget excluding. Then
document all of your static IP addresses so you don't have to go through
this again. Better yet, if you don't need 240 DHCP addresses, narrow the
scope to a more appropriate size and use one of the reclaimed ones from the
pool.

Hi Kurt,

We are running DNS and all IP's are registering. However, our
networkcopiers will not show up in DNS. I guess the person working at my
place before me should have documented the IP addresses of the Newtork
copiers (but didn't..). I'll take the IP's from the driver.

many thanks for your help. PL
