[Kea-users] migration questions

[Peter Davies]

Hi Daniel,
   The "domain-name-servers" option expects a list of IP addresses. Kea 
does not
  resolve domain names as dhcpd did.
  See: 
https://kea.readthedocs.io/en/kea-2.4.0/arm/dhcp4-srv.html#standard-dhcpv4-options


  If you need to see the text, you could manually change the format to 
hexstring, i.e.:
   "data": "'fr-06:/vol/system/share/conf'"

  I've added Gitlab feature request #51, "Text to hexstring" for you.
  see: https://gitlab.isc.org/isc-projects/keama/-/issues/51

  Kind Regards Peter
