SUMMARY
This article briefly explains the differences between superscopes and
supernetting and gives examples of when to use each.
MORE INFORMATION
DHCP Superscoping is used when you need to assign non-supernetted or non-
consecutive IP address subnets to the same physical segment.
For example, if you needed to assign 199.1.1.x and 201.2.2.x addresses
to the same physical network, you could use superscopes or if you needed to
assign 199.1.0.x and 199.1.1.x and did not want to change the subnet mask
to support supernetting.

TITLE : Using DHCP "Superscopes" to Serve Multiple Logical Subnets
Supernetting is used when multiple, consecutive network addresses of the
same Class are combined into blocks. For example, if you need to assign
199.1.1.x and 199.1.2.x to the same physical network and want to change
subnet mask. You would use the subnet mask of 255.255.254.0 and NOT use
DHCP superscopes to assign addresses from DHCP server.
