Your network contains an Active Directory domain named contoso.com. The domain contains a member server named Server 1. Server1 runs Windows Server 2012 R2 and has the DHCP Server server role installed.
You create two IPv4 scopes on Server1. The scopes are configured as shown in the following table.

The DHCP clients in Subnet_Tor can connect to the client computers in Subnet_Mtl by using an IP address or a FQDN. You discover that the DHCP clients in Subnet_Mtl can connect to client computers in Subnet_Tor by using an IP address only.
You need to ensure that the DHCP clients in both subnets can connect to any other DHCP client by using a FQDN.
