Kea 3.0 \u00e4r markerad som den f\u00f6rsta versionen som kommer att ha l\u00e5ngsiktig support (LTS) \u2013 uppdateringar kommer att sl\u00e4ppas under tre \u00e5r.

Produkten inkluderar en fullt fungerande implementation av en server som st\u00f6der DHCPv4- och DHCPv6-protokollen, kapabel att ers\u00e4tta ISC DHCP.

I implementeringen av DHCPv6 finns dessutom m\u00f6jlighet till prefixdelegation.   <\/p>\n<p>Information om tilldelade adresser och klientparametrar kan lagras i olika lagringsl\u00f6sningar, till exempel finns det bak\u00e5tkompatibla l\u00f6sningar f\u00f6r lagring i CSV-filer, MySQL-databaser, Apache Cassandra och PostgreSQL. Parametrar f\u00f6r v\u00e4rdreserv kan anges i konfigurationsfilen i JSON-format eller som en tabell i MySQL och PostgreSQL. Inkluderat \u00e4r verktyget perfdhcp f\u00f6r att m\u00e4ta prestandan hos DHCP-servern och komponenter f\u00f6r att samla in statistik.
