Howdy,
That depends on your timeline. Do you know many non-technical people
still using their Pentium III computers with circa 2001 software
versions? Connected to the Internet?
There are lots of very old networked industrial machines with embedded
computers operated by non-network-savvy people that are still very
much in use.
Think CNC machines in machine shops, SCADA systems, etc. I wouldn't be
a bit surprised to find quite a few 2001-era boxes still in service.
At some level I think there's a good chance that they'd just work. I
wrote a significant amount of the Lantronix terminal server code and it
never occurred to me that I should enforce rules about 127.0.0.0 or
Class D or Class E. It really didn't have much bearing on a terminal
server or the other host-like things we built. If you typed it in, it
would work, if you listened on a port it wouldn't care what the address
was. I would imagine that lots of stacks from back in the day were just
like that.
