Points of Presence

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 (the ISP providing it) and using its own DFP for serving out addresses to its clients under the policies defined by the owner of the PoP. SixXS manages the day to day aspects of these PoPs and provides the software and knowledge to run them properly.

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 and per-pop pages linked below. Trouble Tickets can be found in the Tickets Tracker. PoP Up/Down status updates are available through RSS , @tweetsix, and also on our Status Information IRC channel.

New PoPs

New PoPs 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. To keep the quality high we've defined a couple of requirements for an ISP to become a SixXS PoP. To request a new PoP please provide us a fully filled in requirements form.

Current PoPs

The following maps show the physical locations of the 46 PoPs spread over 29 countries that the SixXS Tunnel Broker system currently manages worldwide. See the list of PoP prefixes for an overview of the prefixes being used by these PoPs.

The PoP status can be Up, Down or Planned.

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.
