We found in general, that because of significant changes throughout the lifetime of the DHCPv6 specification, only the most recent implementations will likely be close to compatible with the final specification.
After some investigation we found the implementations listed below. We only make a brief description of each implementation. A test report of the DHCP implementations used in 6NET is available in Deliverable 3.2.3 [D3.2.3].

8. Cisco DHCPv6 in the IOS
1. dhcp62809.tar.bz2
The dhcp62809 is based on the ISC DHCP3 release candidate 10. The work is located under dhcp6/work.linux-2.2. Only one README file. The development seems to have ceased since September 2001.
2. kamedhcpv6linport.tar.gz
This program is based on the KAME proof-of-concept DHCPv6 server/client. The server can distribute only the DNS (server address and domain name) and Time-zone information. However The implemented client can receive these information, but does not install them in the system configuration files. This implementation is based on a subset of draft 15.
3. dhcpv6.tgz
This program is written by Dhawal Kumar in 1999/2000 for the INRIA IPv6 stack to test the DHCPv6 concept. It is based on draft 15.
4. dhcpv6-1.0.tar.gz
This program was written by Yunzhou Li in 1996 (Very old). It was supported by Digital Equipment Corp. (DEC), University of New Hampshire (UNH) and National University of Singapore (NUS).
This is also a test program as it is stated in the description: “The purpose of this implementation is to verify the feasibility of DHCPv6 and Extensions for DHCPv6 protocols. Hopefully, the code can be useful for the further development of these two protocols and other research on IPv6.” The program is based on the draft 8 therefore it is extremely outdated.
5. KAME
The current KAME dhcp implementation is substantially different the earlier proof-of-concept dhcpv6 implementation. Earlier the goal was to test the best DNS configuration for IPv6. One candidate was the DHCPv6. For testing this concept earlier a very lightweight DHCPv6 was developed and eventually dropped. The current KAME implementation is based on the draft version 26 ofDHCPv6, but does not implement the full DHCPv6 draft. According the authors: “dhcp6c is incomplete and violates DHCPv6 protocol spec, in several aspects. In particular, it does not handle address allocation via DHCPv6. This is, however, rather intentional; the authors believe stateless address autoconfiguration is enough for IPv6 and will not implement the stateful method in the future.”. It implements only prefix distribution, DNS options, rapid commit and site identifier. It is using the All_DHCP_Relay_Agents_and_Servers or the DHCP_Anycast address.
