The DHCP server pings a pool address before assigning the address to a requesting client. If the ping
is unanswered, the DHCP server assumes (with a high probability) that the address is not in use and
assigns the address to the requesting client.


The following example specifies five ping attempts by the DHCP server before ceasing any further
ping attempts:

ip dhcp ping packets 5

address to a requesting client. The default value is two packets.
