I don't remember what the RFC says, but in general, unless the RFC guarantees an implementation should behave a particular way, you are asking for trouble to rely on specific behavior. A great example of this is how round-robin DNS used to work and then how it changed and lots of things broke. DHCP isn't meant to do what you're asking it to do, so I strongly suggest you not use it to solve that particular problem. That said, DHCP supports a mechanism for binding specific IP addresses to specific MAC addresses, even though the assignment is still done dynamically. Yes, this is a bit more work, but at least it's guaranteed behavior. AdamM
