[Kea-users] dynamic hostname Option 12 in a kea pool

Dear all,

I didn't find any option to implement dynamic host-names in kea pool.

Like this in isc dhcpd.

subnet 172.26.250.0 netmask 255.255.254.0 {
  set machex = binary-to-ascii(16, 8, "", substring(hardware, 1, 6));
  set macsuffix = suffix(machex, 6);
  set hstnm = concat("vm-", macsuffix);
  option host-name = hstnm; # Option 12
-->8--

i.e.

  pool {
    range 172.26.250.64 172.26.251.250;
   set machex = binary-to-ascii(16, 8, "", substring(hardware, 1, 6));
   set macsuffix = suffix(machex, 6);
   set hstnm = concat("vm-", macsuffix);
   option host-name = hstnm; # Option 12
-->8--

Does anyone know if this is possible, in kea?

I'm looking into kea, as it's supported (isc dhcp is EOL) and isc dhcp seems 
to have a bug, that might be not fixed?
