Kea is an open-source, high-performance DHCP server from ISC (Internet Systems Consortium). It supports DHCPv4, DHCPv6, and Dynamic DNS updates.
This snap packages the following Kea daemons:
Configuration
Configuration files are stored in: /var/snap/dhcp-kea/common/etc/kea/
After installation, edit the configuration files to match your network: sudo vi /var/snap/dhcp-kea/common/etc/kea/kea-dhcp4.conf
Then restart the desired service: sudo snap restart dhcp-kea.dhcp4
Lease databases are stored in: /var/snap/dhcp-kea/common/var/lib/kea/
Logs are written to stdout and can be viewed with: sudo snap logs dhcp-kea.dhcp4
Services
All four daemons are packaged as snap services. By default only dhcp4 is enabled. Enable others as needed: sudo snap start --enable dhcp-kea.dhcp6 sudo snap start --enable dhcp-kea.ctrl-agent sudo snap start --enable dhcp-kea.ddns
Administration
The kea-admin and kea-shell utilities are available as: sudo dhcp-kea.admin ... sudo dhcp-kea.shell ...

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for Red Hat Enterprise Linux (RHEL) 8 and RHEL 7, from the 7.6 release onward.
The packages for RHEL 7, RHEL 8, and RHEL 9 are in each distribution’s respective Extra Packages for Enterprise Linux (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 7, RHEL 8 and RHEL 9, which is why they’re listed separately below.
The EPEL repository can be added to RHEL 9 with the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
sudo dnf upgrade
The EPEL repository can be added to RHEL 8 with the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf upgrade
The EPEL repository can be added to RHEL 7 with the following command:
sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
Adding the optional and extras repositories is also recommended:
sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms"
sudo yum update
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again or restart your system to ensure snap’s paths are updated correctly.
To install dhcp-kea, simply use the following command:
sudo snap install dhcp-kea
Browse and find snaps from the convenience of your desktop using the snap store snap.
