How to Create a Scope in DHCP Server
Enter the starting and Ending IP address Ranges and Subnet Mask as lengths of bit size and Click Next.
On the Add Exclusions and Delay screen, we can set IP addresses from within the range we defined that should be excluded any IP Addresses. For example, if our range includes the IP address of our network gateway, we probably do not want our clients to use it, so we would add its IP address to the exclusion list and Click Next.
Add a Default Gateway Router for assign IP address for Clients and Click Next
