[Kea-users] Disabling DDNS for PXE clients

[Vladimir Nikolic]

Thanks Darren,

I forgot to mention, we define a client class for PXE clients:

(substring(option[60].hex,0,9) == 'PXEClient')


and ddns-send-update is not available on the client class level (from a 
table on 
https://kea.readthedocs.io/en/kea-2.4.0/arm/dhcp4-srv.html#ddns-for-dhcpv4):

Parameter        Global  Client Class  Shared Network Subnet Pool
ddns-send-update yes     n/a.           yes   yes.    n/a


ISC dhcpd supports it.

Regards,
Vladimir
