Hi All,

Please confirm the following 
>From dibbler-user guide
https://klub.com.pl/dhcpv6/doc/dibbler-user.pdf

pd-pool – (scope: pd-class). Takes coma separated IPv6 address ranges. Each range is defined as fistaddress,a dash and a second address. Defines a range of available prefixes (only prefixes themselves,not their lengths) that will be assigned in specific class.
 An example pd-pool definition looks likethis:
 pd-pool 2001:db8:abcd:: - 2001:db8:abcd::ffff 
It is also possible to use prefix/length notation.
In Dibbler version - 0.8.0 , this format is supported.
We are facing issue when we used Dibbler version -1.0.1.
We need your confirmation like Dibbler-1.0.1 support this kind of pd-pool format or not.

Dibbler is no longer developed or maintained. Please seriously consider migrating to Kea.
See kea.readthedocs.io for details.

How did you come up with this syntax? You should define prefix pool as a single pool, not as a range.
This defines the pool, from which delegations are made. /56 says that only the first 56 bits are important
and remaining bits 57..128 are not, so what you defined here is really 2601:a40:300:1200::/56 (with the
34 and 98 being ignored by the prefix length. So both your notation and your values need to be fixed...

See doc/examples/server-prefix-delegation.conf or take a look at Dibbler User's Guide.

Hope that helps,
Tomek
