Printers not showing on network ping

By banx ·
I was asked to supply a couple of free ip addresses for new pc's on our network. I used look@lan and discovered what i thought were 2 free ip addresses. Turns out they were allocated to network printers. How do i find free ip addresses on my network? as pinging printers returns a packet lost and so i assumed the address was not in use.
Any and all help welcomed.

are you running DHCP

You should be able to look at what your DHCP settings and see which ip's have already been allocated and which ip's have not been.

Static IP's throughout

by banx In reply to are you running DHCP

No dhcp thankfully. Everything has a static address and when looking at a range, say - if a printer has an ip of it doesn't show up as being in use and could therefore be used for a new pc. This is the problem i am having in identifying static ip's in use that don't respond to a ping request.

Ping commands work fine. I can ping any number of printers, but if i want to find say 10 free ip addresses in a range then I'd have to ping all numbers in the range to see if i got a response and if not would then know that address was free. This is time consuming. By using Look@Lan i can easily see what ip addresses are not being used - the problem being printers do not show.
Thanx 4 the help provided thus far....
