To avoid IP address conflicts, the DHCP server checks whether an IP address is in use before assigning
it to a DHCP client.
The DHCP server pings the IP address to be assigned by using ICMP. If the server gets a response within
the specified period, the server selects and pings another IP address. If not, the server pings the IP
address again until the specified number of ping attempts is reached. If still no response is received, the
server assigns the IP address to the requesting client.

To avoid IP address conflicts, the DHCP server checks whether an IP address is in use before assigning
it to a DHCP client.
The DHCP server pings the IP address to be assigned by using ICMP. If the server gets a response within
the specified interval, the server selects and pings another IP address. If not, the server pings the IP
address again until the specified number of ping attempts is reached. If still no response is received, the
server assigns the IP address to the requesting client.
