What are the steps and needed applications to reserved an IP address in the DHPC server?

we must have a server installed on it DHCP service

open DHCP

click on address pool and choose Reservation 

right click on mouse and choose new reservation then enter the MAC address for the PC you want to reserve ip for it and enter the ip then click finish

While setting up DHCP server inside each Scope we can define the address pool and specify the range of IP to be leased out for clients. We can also specify an Exclusion Range with the range of IP's that should not be leased, for example all the IP's that have been configured statically on the machines.

We can also Reserve the IP's for specific machines by binding them to a specific MAC address by specifying this in the SCOPE.

For getting the mac address dont rush to user instead use ARP command to get the mac address. First ping the ip address of the client then arp /a in command prompt.
