DHCPv6 leases hostname

[Kraishak Mahtha]

Hi all,

I am configuring the DHCPv6 setup on my local systems and can obtain an
IPv6 address from my DHCP appliance. However, I am encountering an issue
where the lease file does not display the hostname or DUID of the DHCP
clients.

Sample lease file.

cat /var/db/dhcpd6.leases
# The format of this file is documented in the dhcpd.leases(5) manual
page.
# This lease file was written by isc-dhcp-4.4.3-P1


                                                                     #
authoring-byte-order entry is generated, DO NOT DELETE
authoring-byte-order little-endian;



server-duid "\000\001\000\001-\351\270\267\000PV\200\350\337";



server-duid "\000\001\000\001-\351\270\267\000PV\200\350\337";



ia-na "\000\000\000\000\000\001\000\001-\225\271\351`>_=b\034" {
  cltt 1 2024/09/09 09:35:01;
  iaaddr xxxx:470:edb5:200::1cf {  //Masked
    binding state active;
    preferred-life 27000;
    max-life 43200;
    ends 1 2024/09/09 21:35:01;
  }
}



ia-na "#\316\364\010\000\001\000\001+\204\373O\364\316#\310\033g" {
  cltt 1 2024/09/09 09:49:48;
  iaaddr xxxx:470:edb5:200::1c4 {  //Masked
    binding state active;
    preferred-life 27000;
    max-life 43200;
    ends 1 2024/09/09 21:49:48;
  }
}

I have explored various configuration parameters and compile-time options
to enable the display of hostnames and DUIDs in the lease file, but none
have proven effective. I would appreciate assistance from anyone who has
experience with this or has any insights into resolving the issue.

Thanks In advance
Kraishak
