When running the domain in a private IP block (10.255 and 192.168) you
can run as many DHCP servers as you can make subnets.
A network, 10.255.0.1/255.255.248.0, has 2046 usable addresses, from
10.255.0.1 to 10.255.7.254 (255 is broadcast and can't be allocated for
Each of four DHCP servers are set up to use 10.255.0.1/21 as RANGE and
DHCP server 1 is using a SCOPE of 10.255.0.1 to 10.255.1.255
DHCP server 2 is using a SCOPE of 10.255.2.0 to 10.255.3.255
DHCP server 3 is using a SCOPE of 10.255.4.1 to 10.255.5.255
DHCP server 4 is using a SCOPE of 10.255.6.0 to 10.255.7.255
No overlaps in the scopes ensures that there won't be address-clashes on
If you subnet using a further 1 bit, then you can have twice as many
DHCP servers, each serving half as many clients.
