Sequential DHCP address allocation:
By default, DHCP addresses are assigned psuedo-randomly, using a hash of the client's
MACaddress to determine the IP address that gets assigned. You can configure the
device to use sequential IP addresses instead:
a. Click Network > Advanced.
b. Click to enable Sequential DHCP address allocation.
Because sequential mode does not use a hash based on the client's MAC address, when
DHCP lease expires, the client is not likely to get the same IP address assigned to it.
Therefore, sentential DHCP address allocation generally should not be used.
