提供IPV6连接SIXXS

What is SixXS? SixXS is a so called IPv6 Access Provider. We make it possible for ISP's to enable their clients to access the IPv6 internet using IPv4 in IPv6 tunnels, thus avoiding upgrading the infrastructure between the client and the ISP. More detailed information is available from the main SixXS website. The IPv6Gate is an extra service to help IPv6 deployment.

Why does this service exist? There appears to be a chicken and egg problem in deploying IPv6; ISP's serving endusers don't want to do it yet because there isn't any need for it from their clients, Hosting companies don't do it yet because there isn't any demand yet either from clients. Clients don't need it because there isn't any content and thus there isn't any need for the hosting nor the ISP's to do it. Thus, we made this gateway, which allows users who do have IPv6 to get to all the content in the IPv4 world. If you don't have IPv6 connectivity (yet) you can of course try the SixXS Tunnel Broker.

But my ISP doesn't provide IPv6 yet! You could either pursuade your ISP to support it or get them to install a SixXS PoP or you could setup a tunnel to one of the public SixXS PoPs as SixXS is a Tunnel Broker.

But my computer doesn't do IPv6 yet! Check out the SixXS FAQs where there are numberous examples for most common Operating Systems on how to configure IPv6 support.SixXS is a Tunnel Broker which can provide you with IPv6 connectivity even if you only have IPv4 now.

Can I pick the country where my exit point is? Yes, but only in part, this is because our webfrontends do loadbalancing and failover between themselves. Generally your request will be served from the frontend that you connect to, but there might be failover to other nodes. To use this feature one can use the following construction of URL.

Normal IPv6Gate URL Cluster-specific IPv6Gate URL Description
http://www.example.com.ipv4.sixxs.org http://www.example.com.nl4.sixxs.org Access an IPv6 website over IPv4 using the Dutch cluster
http://www.qq.com.ipv6.sixxs.org http://www.qq.com.nl6.sixxs.org Access an IPv4 website over IPv6 using the Dutch cluster
http://www.example.com.ipv4.sixxs.org http://www.example.com.us4.sixxs.org Access an IPv6 website over IPv4 using the American cluster
http://www.qq.com.ipv6.sixxs.org http://www.qq.com.us6.sixxs.org Access an IPv4 website over IPv6 using the American cluster

Contact information See the SixXS contact pages.
Short notes Some additional notes concerning this service:

  • IPv6Gate: Sites having a AAAA (IPv6) DNS record are redirected to the native variant.
  • Some javascripted URL's don't get rewritten correctly.
  • /robots.txt is hardcoded for every gatewayed site to disallow robots from mirroring any content, this avoids gatewayed sites to become part of eg Google.
  • The real (your) client IP is passed in the X-Forwarded-For HTTP header just like normal gateways/proxies.
  • Logs are kept of accesses and will be used for statistical reasons, the following Apache 2 log line is used:
    LogFormat "%{X-IPv6Gate-Original-URL}o %h %l %u %t \"%r\" %>s %b" ipv6gate
    Except for the above no further information (cookies, post values, headers, etc) are stored or logged, thus this service is quite anonymous, nevertheless in case of abnormal usage, access to the gateway will be denied and we will cooperate with inquiries from authorities.
  • Don't use automated tools in combination with this gateway, thus no spidering or RSS feed reading.
  • IPv6Gate: The gateway works only with an IPv6 host as a client, thus not for IPv4 hosts.
  • IPv4Gate: The gateway works only with an IPv4 host as a client, thus not for IPv6 hosts.
  • Only port 80 (default HTTP port) is supported, as such no SSL (HTTPS) support on port 443.
  • For http://www.google.com.sixxs.org/ use Google Prefs to set a correct cookie so the site doesn't appear in Dutch, as Google figures out that would be the language of the user, a similar solution might apply to other sites who try to detect the language based on the country of origin.
  • Domains of cookies are rewritten causing logins/sessions to sites like Slashdot to work.
  • Contact information for this gateway can be found on the SixXS Contact pages.
