The following is a list of IPv6 tunnel brokers that conform to the principles of RFC 3053 which describes a system with which users can request creation of an IPv6 tunnel on a host called a point of presence (PoP) which, using the tunnel, then provides the user with IPv6 connectivity.

The columns in the table provide the following details:

Name		The name of the organisation providing the tunnel broker, this generally maps directly to an Internet service provider.
PoPs		Number of PoPs deployed
Locations		Locations where the tunnel broker has a point of presence / the number of endpoints where termination can occur.
Subnet		What subnet allocation the tunnel broker provides next to the /127 or /64 for the tunnel.
Tunnelling protocols
		Which tunnelling protocols are provided by the tunnel broker. This has impact on whether one can use a tunnel behind NAT or in cases where the IPv4 address of the user changes often. Check the relevant protocol descriptions for more details, or see this tunneling comparison.
	6in4	Tunnelling of IPv6 packets directly in IPv4, also called 'proto-41' due to the protocol number it uses.
	4in6	Tunnelling of IPv4 directly inside IPv6 packets
	TSP	The Tunnel Setup Protocol. It uses a UDP-based tunnel.
	AYIYA	AYIYA allows users behind a NAT and/or a dynamic address to maintain connectivity even when roaming between networks. It uses a UDP-based tunnel.
	heartbeat	Heartbeat tunnels are 6in4 based but allow for dynamic addresses to be updated automatically without user intervention
Features	RDNS	Whether the tunnel broker provides reverse DNS delegations.
	BGP	Whether the tunnel broker optionally accepts a BGP peering allowing one to announce one's own address space.
	Multicast	Whether the tunnel broker optionally provides IPv6 Multicast over a tunnel.
Registration
		The available registration methods.
	Anonymous	One can use the service without registration
	Signup	One is required to sign up and provide details (at minimum an email address)
Configuration
		What methods are available for configuring tunnels and subnets provided by the tunnel broker
	Script	Indicates that the broker provides a script through the website.
	Manual	That one can set up the tunnel manually if wanted
	TSP	Uses the Tunnel Setup Protocol (TSP), thus requires gogoclient
	TIC	Uses the Tunnel Information and Control (TIC) protocol as implemented by AICCU, AVM FRITZ!Box, Draytek, Motorola and others
	URL	URL indicates that changes to the tunnel parameters can be made on the website (e.g. enable/disable or change the endpoint)
Language		Which languages are supported by the providers web interface and other communication channels.
Prefix		Which IPv6 prefix(es) are used for the tunnel broker. If a /32 is indicated, generally only a portion is used for tunnels/subnets for the tunnel broker or the name of the tunnel broker service that is providing the address space.
Server implementation		The implementation used by the tunnel broker

Implementations

There are a variety of tunnel brokers that provide their own implementations based on different business goals. Listed here are the common implementations as used by the listed IPv6 tunnel brokers.

Gogo6 gogoSERVER

gogoSERVER (formerly Gateway6) is used by the Freenet6 service, which is the first IPv6 tunnel broker service, going into production in 1999. It was started as a project of Viagenie and then Hexago was spun off as a commercial company selling Gateway6, which powered Freenet6, as their flagship product. In June 2009 Hexago became gogo6 through a management buyout and the Freenet6 service became part of gogoNET, a social network for IPv6 professionals.

SixXS sixxsd

SixXS's sixxsd is what powers all the SixXS PoPs. It is a purpose built software for the purpose of tunneling at high performance and low latency. Development started in 2002 and has evolved into the current v4 version of the software.

CITC ddtb

CITC Tunnel Broker, run by the Saudi Arabia IPv6 Task Force, uses their own implementation of the TSP RFC named 'ddtb'.
