Firstly once you have entered a intersection legally it does not matter if the light goes red. Running a red light is entering the intersection on red not being in the intersection on red. Cross traffic is required to give you right of way to clear the intersection.

Living in a city with lots of safety camera that detect both speed and running the red light infractions you get used to them and treat the intersection the same as any other. You approach within the speed limit and you stop on yellow if you can.

It's 100% Facebook's fault. They are the ones that designed the system to not require confirmed opt in before telling the world that you are in a group.
This was a foreseeable consequence of that design decision.

IPv6 will still only get you the residence. Privacy address are used by default for out going connections and are changed regularly by the OS. If you run a server then you advertise a service the you use the stable address in the DNS which is constructed from the MAC if using SLAAC.

The address tagged as temporary below will be different this time tomorrow and they are the ones your browser uses when it wants to talk to the world.

% ifconfig en1 inet6

And there are 35184372088832 /48's available for allocation based on current IPv6 allocation rules. More than enough for everyone to have several.

While I don't know where you live, I suspect that there are fines that can be levied against you if the court was to decide so as well as court costs. For example the fines in NSW are up to 20 penalty units Road Rules for Pedestrians which equates to $2200.

Well here in Australia the polling stations (local schools, churches and town halls) don't change much from election to election (local, state and federal) and if you don't know where to vote the Electoral Commission's web site will tell you. Also since you are required register when you turn 18 and to attend a polling place every election this sort of disinformation campaign just doesn't happen here. You can also pre-vote, postal vote and absentee vote for all elections.

ARIN, RIPE, AFINIC and LACNIC are all Internet Registries. They are the bodies that hand out addresses to companies and individuals. Or were you looking to generate a Perpetual Assignment Process:-)

As for 240/4 it really can't be made usable on a global scale. To many machines can't talk to it. One could use it between consenting machines in a limited way. e.g. between the CPE and a CGN.

No, we didn't skip IPv5. It just was not a main stream protocol.

Mainly because it is self evident to anyone who has had to code software to do anything other than the trivial connect to a server out there.

If you want two clients to be able to talk to each other from behind a NAT you need to deploy a relay server or use STUN and PCP/UPNP and hope that the NAT is configured to support it. This all takes extra development time. Requires extra hardware for the relay server or the STUN server. It's also fragile.

Without NAT each client knows its own address so no need for a STUN server. Depending upon the firewall it may need PCP/UPNP but there to it becomes simpler.

IPv6 is as finalised as IPv4 is. Whats going on now is tinkering and making IPv4 interop better. The main issue with deploying IPv6 is backend software that assumes that IP addresses are 4 octets, dotted quads or has hard coded AF_INET into the socket calls. Most of these issues are relatively straight forward to fix if you have access to the source code. There are address family agnostic techniques to address these issues that are well known.

e.g. replace gethostbyname() with getaddrinfo(), replace "struct sockaddr_in" with "struct sockaddr_storage".

Which isn't true. There are a whole suite of technologies designed to allow a IPv6-only host reach IPv4 only servers. Lots of mobile phones are IPv6 only devices today yet they still reach IPv4 only sites. Going from IPv6 to IPv4 is trivial. Going from a IPv4 only client to a IPv6 only server is harder only because it's hard
to squeeze 128 bits into 32 bits and make that scale to a large number of clients.

Actually it doesn't require the ISP to be completely IPv6 or even deploy the AFTR box as that can be outsourced at the cost of a little more latency.

The AFTR box is still a LS-NAT. It just isn't a double NAT and doesn't have to be in-line nor a be a traditional router.

I would suggest that you really should be looking at your security policies to see if they make sense. DDNS with TSIG or SIG(0) is as secure if not more so than whatever script you are running. This is a decade old technology that has been used in some of the biggest companies in the world, read "Fortune 100" and bigger.

On a mac, system preferences -> sharing, and if you hit edit you can teach it how to register itself in the DNS.

Except there never has been the expectation that communication on the Internet is private without encryption and identification of the party you are talking to. The public has been told this repeatedly for the last two decades. This is one of the reasons people are told to use HTTPS when connecting to banks.
