| Microsoft Press states ;
That a DHCP scope is a range of addresses within a logical subnet and that the DHCP server must belong to that subnet
If you segment a network in to , for example, 20 subnets , can a single DHCP handle this ? or as the book states would we need multiple ( 20 ) DHCP servers ?
Thanks in advance for your replies | |

| In the days of Class full addressing this could have been more complex with subnetting, but lets stick to Classless for now.
You need 20 subnets in your infrastructure, go figure what you need each subnet to be. Set up your DHCP server with the 20 scopes and put a DHCP relay agent on each subnet.
So long as the relay agent knows the static IP address of the DHCP server the relay agent you are sorted.
Personally for 20 subnets I 'recommend' more than one DHCP server but be careful not to overlap the scopes. (ie duplicate IP addesses).
Here is an easy set of scopes for two servers but I'm sure you understand where I'm going.
eg:
DHCPSRV1
Scope:
192.168.0.1-192.168.100.254
Subnet 255.0.0.0
DHCPSRV2
Scope:
192.168.101.1-192.168.254.254
Subnet 255.0.0.0
Make it Class full if you need to | |

| Don't forget to 'Authorise' the scope. |
