Well, I have that. Silently.
When I switched to fibre, I was switched to VoIp, but I wasn't told. I simply get a "thing" with a phone connector, to which is connected the house phone wiring, unchanged.
Yes, I expect that will be the case for most people. Whether the telco uses copper, fibre or carrier pigeons should be transparent to the consumer. An ISDN customer has an NTBA ("terminator box") installed, typically a grey box on the wall somewhere. It interfaces the telephone wires with the S0 bus. I expect Swisscom and Deutsche Telecom will simply replace that with another one, essentially an ADSL modem which interfaces the telephones wires with Ethernet.
The thing is that there are way many more features possible with VoIp terminals or softphones than with POTS. The telephone company hides the data and says it is not possible, but people have figured out how to do it, and do it. It is a 10.* network, probably a VPN on the same router, with no STUN needed (because there is no NAT). People do things like doing several simultanous phone calls, one on the POTs and several on the softphones. I don't know if they are charged or not. They manage to pick up the phone miles away, too. When the phone company catches up, they'll want to charge for all that, of course. Then people will catch up again and simply use the internet connection with a different registrar.
Only if you want to run a server will you need fixed addresses, just like now.
You need an intermediary where you register on each IP change so that others can phone you.
Yes, that's called a "VoIP provider". They also provide the interconnect to the POTS etc.
Well, interconnect to the POTS is an extra. The only service you need outside is the registrar, and there are free providers.
You get both type of addresses for a computer? How know applications which one to use?
/proc/sys/net/ipv6/conf/eth0/use_tempaddr
0 = privacy extensions disabled. 1 = privacy extensions enabled, but not preferred. 2 = privacy extensions enabled, preferred.
It is zero here. I see...
The default on openSUSE is 2, a sound choice for a client. I wonder how you got a 0.
Dunno. I will have to check on other machines, this one has been upgraded from 5.3 upwards. [...] Yes, another machine, more recently set up has a 2. But the only address is: inet6 addr: fe80::203:dff:fe05:17fc/64 Scope:Link (probably because my router doesn't hand out IPv6 addresses)
Type 'b', it is always "2001:db8..."?
"2001:db8::" is like "example.com", it's for documentation only. In real life, it will be one a prefix allocated by your provider.
