failover for mixed subnets

[Luc T.]

Creating the same host statements means that I have to manually change both of them everytime when I need to add, remove, modify them, right?
   
  Is there any automatic synchronization scheme between the two servers? (this seems not very difficult, as we can see similiar scheme for dns primary and secondary servers)
   
  Thanks!

Just create the same host statements. There will be no co-ordination 
between the servers, and there is no need for any - the clients will 
simply get the lease from whichever server answers first.

No, you MUST use a pool, that is part of the syntax.
