List of IPv6 tunnel brokers

This 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) that provides IPv6 connectivity to the user's network.

The 6in4 tunnelling protocol does not function most of the time if the IPv4 address of the host is behind a Carrier-grade NAT. In that case, the AYIYA protocol supported by the discontinued SixXS provided a working alternative.

*Paid services

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 PoP where termination of a tunnel 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	6in4 tunnels IPv6 packets directly inside IPv4, also called 'proto-41' due to the protocol number (41) it uses.
	TSP	The Tunnel Setup Protocol. It uses a UDP-based tunnel, which is used for both tunnelling and configuration.
	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[20]	heartbeat is a side-protocol for signalling the current IP address of a user's 6in4 endpoint. This allows the use of a 6in4 tunnels where the user's endpoint is a dynamic IP address.
Features	RDNS	Whether the tunnel broker provides reverse DNS delegations for the address space they provide over the tunnel.
	BGP	Whether the tunnel broker accepts a BGP peering allowing one to announce one's own address space or see routing information.
	Multicast	Whether the tunnel broker provides IPv6 Multicast over a tunnel.
Registration		If registration is optional or required. Registration requires the user provides real details (at minimum an email address, typically also name and 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 their website that one can run on a computer for setting up the tunnel.
	Manual	That one can set up the tunnel manually if wanted
	TSP	Uses the Tunnel Setup Protocol (TSP) which requires the gogoclient and which can provide configuration details for TSP protocol tunnels.
	TIC	Uses the Tunnel Information and Control (TIC)[21] protocol as implemented by AICCU, AVM FRITZ!Box, Draytek, Motorola and others. This can provide configuration details for static, heartbeat and AYIYA tunnels.
	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 Tunnel broker server software used by the tunnel broker.
