Hi Tim

This looks like Vendor Encapsulated Options, which is well supported in 
ISC dhcpd. Details are in the dhcp-options man page, but I think it will 
look something like this. There are two parts, defining the option, and 
filling in the values.

      The DHCP protocol  defines  the  vendor-encapsulated-options
      option,  which  allows  vendors  to define their own options
      that will be sent encapsulated in a  standard  DHCP  option.

So in the global space define the option:

option space PanoLogic;
option PanoLogic.PanoManagerServerIPAddress code 1 = ip-address;

Then in global space (for all dhcp requests) or any specific scope such 
as host, subnet or whatever fill in the value. You can set different 
values in different scopes if required.

An ip-address can be either a hostname (such as which 
will be resolved by dhcpd at startup, or a dotted quad ip-address (

vendor-option-space PanoLogic;
option PanoLogic.PanoManagerServerIPAddress;
