Make sure the IP address is on the same network segment as the IP address of

After specifying a domain name in the address pool, the DHCP server assigns

Gateway IP Address

DHCP server assigns the gateway address along with an IP address to a
client.

In order for clients to access the Internet using a domain name, the DHCP
