By the way, IPv8 can also be used to disable checksums and for certain "security" tricks on internal networks. @ > There are macros to test the version and options bits... @ > @ > You have to use "&" and not "==" to make sure you @ > are testing just one bit at a time.

IPv8 takes that bit, sets it to 1 and then "borrows" the other bits. A more accurate description would be... "@ But 4 = 0100, 6 = 0110, 8 = 1XXX, etc." @ I'm not sure if you're aware of this, but there is an IPv6 being developed by @ a large number of people. @ I have been at this over 20 years...I am very aware of IPv6. Have you ever seen some of the "private" opinions about IPv6 from some of the experts that designed it...??? @ Hmmm. @ @ I'm *very* concerned that you're doing this. @ I am glad that you are concerned. Maybe you can help launch and administer the Australian/New Zealand Galaxy? @ Have you submitted any documentation on this to the IETF ? @ The IETF is only concerned with a small subset of the IPv8 OuterInternet. Galaxy 0: StarGate 0: has been allocated to the Legacy Internet. The IPv8 OuterInternet is built on the "outside" of the Legacy Internet. @ Protocol numbers aren't there to be chosen lightly, they should be @ registered with the IANA first, before use. @ The IANA is only involved with the Legacy Internet. The IANA has nothing to do with the OuterInternet. The OuterInternet will be administered by true "trusteeships" and not individuals. -- Jim Fleming UNETY Systems, Inc.
