How To Install And Configure Kea For Ubuntu Or Debian
In this video, we show you how to install and configure the Kea DHCP server for Ubuntu or Debian
What we’ll be covering is how to set up a basic DHCP server that supports IPv4
Although there is a lot more you can do with Kea, including monitoring and managing it from a server with a GUI

Fantastic video!!! I have installed four KEAs and for the backend, I've chosen MariaDB for DHCP leases. The problem is when I do a lease dump with the kea admin tool to a CSV, truncate the table, and then upload the same CSV with the kea admin tool, the DHCP shows a lease update error and can't update any of the existing IPs. Also, if the CSV has more than 500 records, it can't be uploaded… Have you ever encountered this issue? My plan is that if I need to upgrade, I take down one of the four, upgrade it, export the leases from the database to a CSV, change in the specific to read mem file, bring it back online, and then take down the other three, upgrade them, apply the new schema, import the CSV file, and open the other two to handle traffic. Then I immediately take down the one with the CSV to ensure there's no downtime at all.😵💫😵💫
Good Video FR
Thanks G
great video. i've used isc-dhcp for years and saw there was a way to just migrate existing config to kea but I wanted to try building it from scratch. your video was very helpful. thank you.
Instead of "sudo su -" you can just do "sudo -i".
I have two DHCP server (primary and secondary) to prevent problems in case of hardware failure. I know KEA doesn't have primary and secondary, but a "HA" feature equal to support that. I read, i need an additional "CA" to handle that. I'm a bit confused to do that, because in my mind "CA" stands for "certification authority" 🙂
What is your recommendation for managing with a GUI?
Thank you for this instructive Video!
Since editing the configuration is error-prone due to the JSON-Notation, i found this Command particularly helpful: kea-dhcp4 -t /path/to/config tells you all the omitted or superfluous commas, brackets etc.
I've been enjoying your videos and subscribed to your channel. Just a suggestion. How about doing a video on tying Kea DHCP to Bind9 to create, update and delete DNS records when clients get an IP address. I have done this in the past with ISC-DHCP and rndc keys, but it looks like Kea uses TSIG keys and I'm having trouble finding out how to integrate this with Bind9. Thank you and keep sharing the knowledge!
Congratulations for the video very clear explanation. I am deploying KEA DHCP server in my company. – How to register subnets and pools and register MAC, gateway, DNS and Domain addresses so that the DHCP KEA server assigns randomly identifying the "IPs" available in the pool and delivering what is available to the machines. Thank you, a hug from Brazil.
You rock!
On my Ubuntu this was not working, so I read the note and remove -server
apt install isc-kea-dhcp4-server -y
Reading package lists… Done
Building dependency tree… Done
Reading state information… Done
Package isc-kea-dhcp4-server is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
isc-kea-dhcp4
E: Package 'isc-kea-dhcp4-server' has no installation candidate
