My question is: What would be the best way to avoid customers to just grab
unused IPs for their workstations? The only way I could do it now is
assign all the untaken IP to a Nt workstation, but that is cumbersome and
The only suggestion I can offer, is to get a network admin who knows what
First of all, 255.255.254.0 is not a class C, it is 2 class C's (or 1 /23,
and they're now known). Using that mask, and if, indeed, your upstream has
allocated you a class C, I'm surprised they haven't nailed you yet for some
'unusual traffic' on your link...
Next, you should be allocating customers only what they need. If they need 1
address, give them a /30 (with the gateway on your router, leaving 1 IP at
the customer end. Similarly for customers requiring more addresses, assign
them appropriately sized subnets.
What configuration restraints?
Whoever set it up being incapable is the only restraint I see here.
