size.  The number available would be to large to fit on the screen.  The percentage used 
would most likely remain at 0% due to the sheer number of available IPs.  

Second, a new category of allocation is shown here.  This is “Prefix” which is short for 
Prefix Delegation.  This refers to the subnets allocated to end point routers for use on 
the interior LAN due to the absence of NAT in IPv6.  Available subnets and percentage 
of subnets used are both calculated and shown here as they are likely to be a 
somewhat finite resource.

As was the case in DHCPv4, you can click any of the subnets shown to see a list of 
devices that are using addresses (or prefix) in that subnet.  Currently, graphs are not 
calculated and shown here.  That will come in a future version.

Also new in version 6.1.0 is Search Sessions for DHCPv6 (see Figure 9.9).  Again, this 
is a similar concept to its counterpart in DHCPv4.  There are some key differences, 
however.  

On the search parameter side, a new search target, DUID, is introduced.  DUID is an 
identifier that is key to DHCPv6 address allocation.  It sort of takes the place of MAC 
address in this respect.  Option 82 searching (DHCPv4) is replaced by Option 18 
(interface ID) and Option 37 (Remote ID) searching (DHCPv6) as these are now 
separate options.  The MAC address and username may not be present, and as of 
version 6.1.0 will not be present/searchable.  

On the search results side, you may notice that MAC address and username both have 
a column but are not present.  MAC address will appear in future versions if it is 
available.  Typically speaking, in DHCPv6, MAC address is not available to the server
