Static Allocation Not Working

[Douglas Armstrong]

Do not include static addresses in range statements. The only way that 
the server knows a static address is given out is if it responds back to 
a ping when the DHCP server attempts to ping it before giving it out as 
a dynamic address. A quick search for "ping check" on the list archives 
will give you some threads with much more info.
