ISC DHCP DHCPv6
The original ISC DHCP software package includes IPv6 support for DHCPv6 since the 4.x releases, with basic DHCPv6 server, client and relay functionality. Not all IPv6 features work on all platforms.
The ISC DHCP package is split into three separate programs: dhcpd, the DHCP server, dhclient, the DHCP client and dhcrelay, the DHCP relay agent. These programs all support both IPv4 and IPv6, however, client and server can only operate one protocol at a time — for dual support they must be started separately for v4 and v6.
The ISC DHCP version 4.1 is not shipped by many operating systems in the package distribution systems — the software has to be built by hand from sources.
