RE: Two IPv6 Hosts Communicating over IPv4 network

for supporting of below processing, each host must be configured dual
stack.
then you can may adapt BIA or BIS to this situation.

refer to :
Dual Stack Hosts using the Bump-In-the-Stack Technique (BIS) (RFC 2767) 
Dual Stack Hosts using 'Bump-in-the-API' (BIA) (RFC 3338)

Subject: (ngtrans) Two IPv6 Hosts Communicating over IPv4 network


Dear all,

I would like to have two hosts, which run IPv6 application on Linux,
communicate each other across a commercial network. But there is no IPv6
support in the commercial network.

I guess IPv6/ICMPv6 packets must be converted to IPv4/ICMPv4 packets in
host b4 they enter the IPv4 network. Likewise, IPv4/ICMPv4 shall be
converted back to IPv6/ICMPv6 once they reach the destination IPv6 host.
I have a few questions as follows.

1) Has such work been implemented in Linux or other OS?
2) If no, which RFC or draft addressing this issue?
3) Does my scenario need to touch 6Bone, since only two IPv6 hosts are
involved?
4) Anything else need to be done apart from conversion of IP/ICMP?

Any suggestion and comment are highly appreciated.

Best regards,
Zhigao
