Restric the IP's use
Can I use linux to restric the use of some free IP's in a subnet (i,e, lock them).
Knowing that. I'm using static IP allocation (I don't use DHCP).

When you say restrict, are you talking about when using linux as a router/firewall? Or just stop other machines from being able to assign themselves the IP address?
