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.
VENDOR ENCAPSULATED OPTIONS
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 pano.example.com) which
will be resolved by dhcpd at startup, or a dotted quad ip-address (184.108.40.206).
option PanoLogic.PanoManagerServerIPAddress host.example.com;
