Points of Presence
The SixXS system provisions multiple PoPs. A PoP (Point of Presence) is a router/machine serving IPv6 in IPv4 tunnels.
In RFC3053 IPv6 Tunnel Broker terminology a PoP would be called a Tunnel Server, while SixXS is the Tunnel Broker.
Each one of these PoPs is under complete control of the owner and using its own DFP for serving out addresses to its clients under the policies defined by PoP's owners.
SixXS manages the day to day aspects of these PoPs and provides the software and knowledge to run them properly.
To keep the quality high we've defined a couple of requirements for an ISP to become a SixXS PoP. Additional PoPs are welcome from all around the world.
Which PoP should I use?
What can SixXS do for an ISP?
What can SixXS do for endusers?
The status of the PoPs can be checked on the PoP Status/Overview page.
Trouble Tickets can be found in the Tickets Tracker.
PoP Up/Down status updates are available through RSS
and also on the IRC channel.
New PoP's
New PoP's are always welcome to join, which is completely free, the PoP is not required to be public and control & usage depend on the policy of the owner.
Contact us and ask for more information when needed.
You will at one point have to fill in the requirements form, though one can submit that at once to get the short process jumpstarted.

Current PoPs
The following maps show the physical locations of the 38 PoPs spread over 20 countries that the SixXS Tunnel Broker system currently manages worldwide.
See the list of PoP prefixes for an overview of the prefixeses being used by these PoPs.
The PoP status can be Up, Down or Planned.

Former PoPs
Following PoP's where previously also available but where shutdown due to the shutdown of the 6bone.
PoP Naming Scheme
PoPs are named according to UN/LOCODE in the format of a two letter country code followed by a three letter city code and a two digit sequence number.
Tunnel Naming Scheme
Tunnel endpoints will have two DNS forward and reverse entries:
gw-tunnelnumber.city-sequencenumber.tld.sixxs.net
cl-tunnelnumber.city-sequencenumber.tld.sixxs.net
The gw stands for Gateway and is on the side of the PoP, ::1 in the /64.
That address should only appear in traceroutes.
cl stands for client and it is the endpoint of the client, ::2 in the /64.
Examples:
- gw-20.ams-02.nl.sixxs.net - Gateway endpoint of tunnel 20 on PoP nlams02.
- cl-42.dub-01.ie.sixxs.net - Client endpoint of tunnel 42 on PoP iedub01.
- cl-13.pub-poz-01.pl.sixxs.net - Client endpoint of tunnel 13 on public part of PoP plpoz01.
