SixXS IPv6-IPv4 and IPv4-IPv6 Website Gateway/Proxy

Welcome to the portal for the SixXS SixXS IPv6-IPv4 and IPv4-IPv6 Website Gateway/Proxy. The portal gives IPv6 capable http-clients access to IPv4-only websites and IPv4 capable http-clients access to IPv6-only websites. It thus acts as a Web Proxy between IPv4-IPv6 and IPv6-IPv4.

Note: This service is goverend by an Acceptable Usage Policy

With a few gateway-side tricks all the external hosts on the websites get .sixxs.org or ipv6.sixxs.org (IPv6 to IPv4) or ipv4.sixxs.org (IPv4 to IPv6) added to their hostname thus furter queries will end up going through the gateway.

The visited websites will find the following User-Agent in their logs:
IPv6 to IPv4 Gateway: SixXS-IPv6Gate/4.1 (IPv6 to IPv4 Gateway; http://www.sixxs.net/tools/gateway/; info@sixxs.net)
IPv4 to IPv6 Gateway: SixXS-IPv6Gate/4.1 (IPv4 to IPv6 Gateway; http://www.sixxs.net/tools/gateway/; info@sixxs.net)
The original User-Agent string is prepended. Note that according to RFC2068 appending the original User-Agent should work, but because some websites only check the first token, we had to append it.

When they get enough hits they might be hinted that IPv6 use is rising and maybe we can pursuade them this way to start making their websites natively IPv6 accessible.

What Internet Protocol am I using?

You are using IPv4 and are coming from 107.20.129.212.
Apparently you don't have a IPv6 connection yet, check the FAQ below for more information.
You might want to check out the SixXS Tunnel Broker to get free IPv6 connectivity. You can use the IPv4Gate to browse IPv6 websites without any configuration changes or without having to install any additional software.

How to use the IPv6Gate

Append ".sixxs.org" or ".ipv6.sixxs.org" to the hostname of the website you want to visit.
Examples:

How to use the IPv4Gate

Append ".ipv4.sixxs.org" to the hostname of the website you want to visit.
Examples:

For whom is this service?

The IPv6Gate service is available for all IPv6 capable HTTP/1.1 (+) clients.
The IPv4Gate service is available for all IPv4 capable HTTP/1.1 (+) clients.

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.

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 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.
