????? I can understand a fee for a static IP4 - they've run out, after
all, and people are fighting over them ...

Don't ISPs get a 2^64 allocation of IP6 *network* addresses? They should
just allocate one to your router and that's that! Still, I wouldn't put
it past them to charge extra for what should be free.

That's not what a static IP brings, that's what a "globally known" IP
brings - if your router advertises its address to something like dyndns
every time it starts, you'll have the same result. Snag is, that's a
chargeable subscription, I believe.

That's why I need to dig and investigate :-) My first ISP in the days of
dial-up allocated a static IP as a matter of course. Not only was it
useful to use, it suited them because customers could only use it on one
computer at a time otherwise routing got screwed up :-)

Then we went to broadband, and in effect it was static because the
modem/router was always on ...


It'll be interesting digging through all this. Just try and make sure
you use your router as a firewall. I think my router drops all incoming
connections BY DEFAULT. But I can open up any port I want, either to
re-route to an internal computer or just pass through to it.

My first investigations would be (1) how do I advertise my router's
network address on dyndns, and (2) once the outside world knows my IP,
how do I let stuff through my router/firewall.
