If you are looking for technical answer, yes, as netdog said Wikipedia has list of these different encapsulations, which of course need to be De-encapsulated as well:
»
en.wikipedia.org/wiki/IP ··· chanismsOtherwise it may to helpful to learn more about what you are trying to accomplish and what you have to work with? most commonly someone wants to get on IPv6 internet as client or server before ISP and/or hardware can support it, in which case if it's the ISP you may want to signup for a service like he.net's tunnel broker at »
ipv6.he.net which uses 6in4. (tip: many newer routers can support this directly in the router GUI/web interface, if using a real CISCO router in the CLI)
One common misconception is that all ISPs have to do is an a router or server so that clients can talk to IPv6 internet, this is not the case. The encapsulation are used for TEMPORARY fix to get IPv4 network segments on IPv6 internet, and for TUNNELS/BRIDGES between islands of IPv6 (or IPv4 in the coming years, as IPv6 takes over as primary, or for private networks).
IPv6 only connections are unlikely to occur for another 6-10 years. Instead IPv4 will move to CGN carrier grade NAT to continue providing IPv4 access, so your bilingual English/Spanish hardware and software will not need any special treatment to continue talking to IPv4 internet. When it does start you won't be able to access non-upgraded systems, unless they are your own or a friend's endpoints and you setup a TUNNEL/BRIDGE using a variation of 4in6 protocol (most of the protocols on Wikipedia above are variations of 6in4)
p.s. yes i know i got a bit wordy... was trying to cover all bases... given limited data on what you are looking for)
