Title: [ISC vs. KEA] Is the effect of this DHCP option the same for both or not ?
Post by: nero355 on January 28, 2026, 12:14:30 AM
I was wondering if the following two function the same way or not :

ISC has : Ignore Client UIDs
QuoteBy default, the same MAC can get multiple leases if the requests are sent using different UIDs. To avoid this behavior, check this box and client UIDs will be ignored.

KEA has : Match client-id
QuoteBy default, KEA uses client-identifiers instead of MAC addresses to locate clients, disabling this option changes back to matching on MAC address which is used by most dhcp implementations.

I had the ISC option Enabled so now I have the KEA option Disabled and was wondering if the result is the same :

Ignore Clients sending anything else than their MAC Address when requesting a DHCP Lease ?!



I have tried reading about it in the KEA Documentation on their website, but there was nothing related to this that I could find...

** BUMP **

I am really curious if this is the case or not :

I really liked the ISC DHCP option and hope the KEA DHCP option does the same :)
