AICCU (Automatic IPv6 Connectivity Client Utility) is a popular cross-platform utility for automatically configuring an IPv6 tunnel. It is free software available under a BSD license. The utility is originally provided for the SixXS Tunnel Broker but it can also be used by a variety of other tunnel brokers.

History and development
AICCU was written and is maintained by Jeroen Massar. Various patches from other persons have been incorporated, these persons are acknowledged in the field for their contributions. AICCU is the successor of the Windows-only and Linux/BSD-variety of the Heartbeat tool that was provided by SixXS, solely to use the Heartbeat protocol. When the AYIYA protocol came into existence it was decided that to support this new protocol it would be better to merge the Windows and Unix trees into one program and give it a better appearance. The name of the Heartbeat tool was then changed to reflect that it did more than providing mere support for the heartbeats.
Award of excellence
AICCU has won the Award of Excellence in the Implementation Category of the 2004 Edition of the IPv6 Application Contest.
Supported protocols
The following tunneling protocols are currently supported:
AICCU primarily uses the TIC protocol to retrieve the configuration parameters of the tunnel automatically that the user wants to have configured.
Support for other tunnel brokers
AICCU finds available tunnel brokers by looking up the TXT DNS records from "_aiccu.sixxs.net". The latter allows a local network to add their own tunnel broker(s) by adding records in the domains configured in their search path. Non-local tunnel brokers can be added by requesting the SixXS staff to add an entry to the global DNS records.
Supported platforms
The following operating systems/platforms/distributions are supported by AICCU:
Various distributions have an AICCU package included in their distribution.
Usage
The main usage of AICCU is in combination with the SixXS tunnel broker service.
There are other ISPs who have implemented parts of the protocols that AICCU support, for instance the Czech ISP NetBox uses AICCU to configure tunnels automatically for their users by providing a TIC (Tunnel Information and Control protocol) implementation that ignores the username/password/tunnel_id but uses the source address where the TIC connection originates from to determine and return the tunnel configuration using the TIC protocol, which AICCU then uses to configure the tunnel.
