This popular software package among company administrators DHCP If it changes: version 3.0 is expected soon as part of development, manufacturer ISC has revealed almost all sources of almost all commercially introduced extensions. Kea is a versatile distributor of the IP address and network configuration that replaces the ISC DHCP server distributed in a large -scale company network; For a long time, it was considered a reference implementation for the DHCP protocol.
Nevertheless, ISC DHCP also had weaknesses, which was partially due to monolitical structure. The kea is modular and expandable. In this way, the administrators can decide for their respective examples what work they should do. Except for tasks, they limit complexity and increase security.
Like the pioneer ISC-DHCP, Kea has also been developed by the Internet System Consortium (ISC). It is an American non-profit organization that licenses the software according to the Mozilla Public License (MPL). Programmers are firmly employed.
So far, ISC has generated its funding from the income of commercial Kea extensions, which mainly require large company networks. Meanwhile, Kea-DHCP is popular and companies are supporting development using support contracts, so that further development is safe, ISC explains steps to disclose Source.
These results are (hooks):
, Class CMD -ADD, update, deleted and accessed DHCP client classes without restarting the DHCP server.
, DDNS-Tuning Control of the structure of DNS host names, which transmits the DNS DNS server by a dynamic update.
, Flex ID Identification of DHCP devices depending on almost any characteristics of DHCP requests.
, Forensic protocol – Configy log output and logging.
, GSS-SIG-Equiphy The conduct of DDNS updates via GSS-SIG to secure safe transmission of DNS updates to Windows-AD Domain Controller.
, Host cash – Internal memory for questioning for other systems from DHCP server, e.g. B. Radius Server.
, Host CMDs Management and management of DHCP reservation in a SQL database.

, Lease querry – DHCPV4 and DHCPV6 Leasekwei (Questions of lease information from network).
, Boundaries – The limit of the number of DHCP answers for some networks or equipment.
, Pingal exam – Sends an ICMP eco (ping) before allocating the lease.
Two extensions remain for fees:
, Baking configuration -AEA-DHCP configuration does not save in a file, but in a SQL database to distribute it automatically in many kea DHCP examples.
, Role-based access control Using API Access until Kea DHCP configuration using X509 certificates.
In addition, KEA should include 3.0 new tasks, including:
, Hub-and-spoke in ha module: A single Kea Dhcp-Failover server can serve as a backup for several primary kea DHCP servers in a high availability configuration (HA). Till now, only one-to-one relationship in Ha configuration was possible.
, Regular price While interrogating DHCP client classes.
According to ‣V6-only-printed RFC 8925: Server double-stack DHCP customers announced that they should no longer use IPV4.
Innovation is available for testing from the current development version 2.7.7. Stable version 3.0, which is also suitable for the production environment, is to be completed in summer of 2025. ISC now hopes that corporate users will continue to fulfill the support contracts to further develop the Kea-DHCP.
