Title: Kea DHCP Question
Post by: EvilAchmed on June 09, 2025, 07:11:50 PM
Hello Everyone,

I have been looking at migrating to Kea from ISC.  I have played with it a bit in my lab but have one last question to answer before I make the move.

Is there a way to remove a dynamically assigned DHCP address from the Lease database like in ISC?  If the answer is no is there any place to find out if this feature is going to be added in a future update or request that this feature be considered?

Thanks for your consideration.

Send a dhcp release with the client that currently holds the IP.

E.g in windows

ipconfig /release

That's not really a reasonable option.  It may work on Windows but that doesn't work on any IoT devices like IP Camera's or Smart Bulbs.

Any other opinions?

Thanks

Yes, you could reset those devices to default.

That is my opinion, whereas Monviech's reply was a factual and reasonable response by an expert to an insufficiently-defined request. I realise that sounds a "tone-police" style of advice by me, please take it as kindly.
