This may be of interest to a few people here. Future projects?
Kind regards,

Hi Olivier,

Heidi passed me your message.

I was amused when I found out about this but IPv6 *can* be run on some really old hardware. I suppose it's not such a surprise because the computers that sent astronauts to the moon are far less powerful than almost anything you have been able to buy for years now and IPv4 and IPv6 are not so very different. After all, if DOS could do IPv4 with KA9Q and early versions of Windows could by using Trumpet WinSock then those same computers should be able to run software that does IPv6, should it be written.

The Contiki project is an O/S with IPv4 and IPv6 support. As the web site explains, it has been ported to a whole range of old, low power systems including the Atari 8-bit family! (first released in 1972)

It is possible to run IPv6 on some really old hardware. I expect the user experience is not much fun if you are used to very responsive systems but it can be done.

Best regards,

Leo
