and night).
Looking at RFC-1884, the addressing is actually pretty neat. The last 48
bits
being the ethernet address for example, leaving 80 bits. Probably another
good
MAC address would be the AX.25 callsign which, while currently 56 bits, is
very
wasteful. Each position in the callsign is given 8 bits, where really only
6 bits
are used (26 Alpha, 10 Numeric, or 36 total for a good 6 bit fit with room
to spare).
But this gets pretty hokey, really fast. For years now, the Unix group has
used
computed MAC addresses for ARP, etc. That's probably a better route. That
a callsign and SSID will be converted to a 48 bit (ethernet compatible) MAC
address. This comined 128 bit address being refered to as a Unicast
address.
But the real question, I guess, is who do you coordinate the top 80 bits of
the
Unicast address with? I guess we would have a regional provider, or maybe
a
global provider?? Would UCSD be willing to be the Global Provider for
AMPR/6?
Am I missing the boat there... It seems to me, the only path to go would
be for
each region to set aside 8 bits for a regional AMPRnet. That way the
routing is
handled correctly upstream.
Now I'm-a-gonna go eat this big ole possum and armadillo stew fer
Thanksgiving,
umm-ummmh... and hope you enjoy your family as well...

Linux in (developement) kernel version 2.1 already supports IPv6 AFAIK. It
will surely support it in 2.2 kernel.

Subject: IPv6, and AEA final
IPv6 is one of those things I look at every now and then, but always
end up shaking my head at the complexity. I'm probably un-informed
and haven't thought it through. What exactly is the advantage of
IPv6? I'm thinking it removes the 32 bit address restriction, but does
it really do anything better? Is it going to be like Win95 vs Win3.1
where we get 32 bits vs 16 bits, and need a 1.6 Gig drive instead of
a 20 Meg drive :-)
Re: The future of Ham radio, and AEA (and others) marketing failure.
Go get a pilots license. The test is just like a Ham license. Study
the book, take the test. All the answers are in there. Even little
Jessica could pass it (RIP)...
Things like resistor color codes, and sling-psychrometers were
important in my old radar days. I actually had a soldering gun, and
only wimps used an iron :-) Complexity was a dual-pentode, and
a flip-flop made from 12AT7 tubes. The way you trouble-shot a
Height-Finder RHI scope was to move 12AT7 tubes around until
the problem moved. Then you took out your man-size needle nose
and soldering GUN (ar-ar-argh) and slapped in a new man-sized
capacitor or 1 Watt resistor (ar-ar-argh). Only wimps in the
computer shop used circuit card jigs and threw the cards away...
Today it's different. I can still trace signal paths, and power
distribution. Read schematics etc. But when my radio dies, I
take it to a Ham convention and trade it for a stuffed doll for my
neice. Then I go over and buy a new one. I checked, it's really
cheaper to throw it away then to repair it. $45 an hour my ass...
So really, Ham radio is merely a communicator hobby for 98%
of the active licensees. Many can't program in any language,
never build anything electronic, but like to meet with a group of
people they like being around. Most new Hams only want to
get on HF because old Hams make them think it's where the
action is. But a few days or nights of listening to"CQ Contest",
or those old windbags (they always sound like they are 150
years old) on HF is REALLY boring. Then if they do key up
they get run off because a sched is imminent and we've owned
the frequency since 1954 assholes come on.
I say get rid of the license, get rid of the bands, let everyone
transmit wherever they want. Wouldn't be any different from now.
After seeing Hams fighting over FCC license callsigns, and
slobbering all over themselves when they get one, I think
anthropologists are right... We have dropped way too many
chromosomes in evolution. Anyone with a vanity call is highly
suspect. Shoot on sight before it breeds...
