charset=us-ascii; format=flowed Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi, I have native ipv4 and ipv6 and a lot more ipv6 addresses available than ipv4. Is there some way of having (externally routable) multiple ipv6-only interfaces behind that one ipv4 address? let's say the machine name is ipv6-a.some.name.whatevertld and its interface has one /64 and only that ip. can I make a machine call it ipv4.some.name.whatevertld, give it its own ipv4 (and its own ipv6 - call it ipv6-b.some.name.whatevertld) address and configure=20 it to route ipv6-a packets to the right machine? Otherwise my ipv6-a machine will only be accessible by someone with ipv6 functionality. Basically i'm asking if I can somehow put an ipv6-only machine on the internet and have it accessible via ipv4. I dimly remember something about 4to6 and 6to4 translation - is that how? thanks, --=20 J. --BCae6wrs8Fws5nyx Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE8n3tWhxW11Ccvv9/s8o7QhFzNAUFAmFU9v0ACgkQs8o7QhFz NAXPGBAAqSMwYZ4fuye+DzpWkCS7EmiUk9/p7gRt0a/5zz8IICUvCU4qu+0E4sBn nr+HXHuwH4b0VzaZLVzEcuGh1WdzRcoKL95axuTH5RXpJkRpgsOwCE4U6g+n95+B q/9zxEqq7lMsDnkLQikmeVTADkdqrbxAVYF9ePjXNlY3xgJt54zS9JLMEP1MTLF5 c/lRbN18wKKSGu+vvmW7yDlJ/1WULmFW610f+j1bdK3aCqPS54OAEYTFHgBX7pKa e9lUH3ag0fuVzgF7S9F8p7x8NFn4VRuZ7eXRHD+KklvP1iPBeeO2jvSZjZ26L3CW WL85eqwx9csAnKlYQCAvSfRVcDOHoTy82Nbe4syZ6ish60KEcmhXPEdUkaYdTk2g LV7TjoX2uzZSkWDgjvL75aFuP9OP2cMz3SQZWs/dCJfVZNyR1WlyvPju9jvDAFQ9 gNLCbb5KR19ufiAYFIrJyAefKYloyqz2o/2PKQwDpv4O9riTnWMfdjHrR/d2f5c+ wozUWLxA+E8Pa0Bh5rBu+7nFeH1Smk1nj1fmgl3s8vPo8rd8BNVs9W5mFzJ/bDZK 0yXtWyBbU1fnEYtQIVZ81tlAH73U8hUBWgVGj1/PGWGCu5gQ5bcB6qMwE7kKb0cL rY0NDo5XopO2kR9Hv1SZMi0Qs1O7ohi/4Q7JoooS5bta4z/nTw0= =O3ju -----END PGP SIGNATURE----- --BCae6wrs8Fws5nyx--
