We have ~100 physical nodes which can host a large number of VMs apiece. We need to set up dhcpd on one machine to distribute addresses in a predictable fashion based on MAC address.
We'd like to go with a scheme such as:
Physical host address: A.B.255.X VM address range: A.B.X.Y VM MAC range: 54:52:00:00:x:y
x = Hex(X) y = Hex(Y)
I found this post which would let us set up A.B.X.* pools based on MAC prefix 54:52:00:00:x:*, but this has two drawbacks:
- Each pool is dynamic, so no direct y<->Y mapping
- We'd have to explicitly name all the pools in the dhcpd.conf (~100 of them)
Is there some way to succinctly specify a scheme like this in dhcpd.conf?
