IPv6 daydreams

Mon Oct 17 09:43:52 UTC 2005

 From an end-user:

I dont know what I should need an /64 for but it's barf, barf anyhow.

My routing table is telling me I have got a /124 only:

The tunnel (network) *::0
The end of the tunnel *::1
Me *::2
The tunnel broadcast *::3

Right now I have the impression we are only enusers.
Right now I have the impression we are all connected to the same
university PC running BSD something.

Ok, today I have some NATted stuff that would be fond of its own
ip. Kicking my NAT-box out I could grow my hair again. No more
worring who needs what port and why.

Beware!

Who is printing all those bank listings on my new printer. It
was a wholesale networkprinter. Just plug it into the power
and print. Must have been stolen from the bank of china because
it is all chines companies.

And why is that van with the ice cream waiting in front of my
neighour? It is me who ordered the icream. They have thrown
out their freecer. I dont know why. It was working perfectly.
I had no problems connecting it to my wlan and ordering. They
did not even care about my bank account beeing empty. They told
me I had enough credit to by their company.

Sorry I have to stop now. Some policemen want to talk with me
about a major fraud done with my IPv6 tunnel.

See you later :)
