IPv6 and IPv4 gateway services

SixXS is providing IPv6 and IPv4 gateway services through the use of domain names. Suppose an IPv6 only host wants to access IPv4-based www.cnn.com, the URL is www.cnn.com.sixxs.org. Converserly, for an IPv4 host to access IPv6 servers such as ipv6.google.com, the URL will be ipv6.google.com.ipv4.sixxs.org.

Great work. The is another way for people to access IPv6 web sites without using tunneling.
