To specify the TCP port number on the DHCP server, complete the tasks in the

following table:

Determining Whether an IP Address Is Available on the Network

Before the DHCP server assigns an IP address to a DHCP client, it must ensure

that the IP address is not already in use on the network.

To verify that the IP address is available, the DHCP server sends out an ICMP

Echo request, called a ping. If the server fails to receive a response to the request

within the specified timeout period (ping request timeout), the DHCP server offers

the IP address and grants a lease to the client. If the DHCP server receives a

response to the request, the IP address is unavailable and therefore cannot be

offered to the client.

By default, the DHCP server pings the IP address of a prospective DHCP client

only once before declaring it available.
