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