In my opinion NAT is a hack that makes lot of things harder than they should be. STUN and TURN are services that are created because there is no easy way to connect two hosts between different NATs. UPnP for port forwarding is another. CG-NAT is even worse. I have heard of so many people having problems with it.

Breadcast is messy. It is like screaming into a room and waiting for an answer. Multicast lets the computer decide if it wants and needs to listen to a specific group message.

IPv4 didn’t have cidr from the beginning. They only had classes. IPv6 was designed with complex routing and sub routing in mind.

They never wanted to worry about address space size again. And this makes subnetting much easier. I have a /56 allocation so I could do 256 /64 subnets. I hope that at some point home routers will have the option for seperate subnets built in. This way you could easily have guest, IoT, work or whatever networks without NAT.

One thing you have to consider though is that the minimum network size that allows autoconf is /64 and that because of the privacy extension a device usually has 3-4 IPv6 adresses.

IPv6 changed some things. First and foremost it has a huge address space:

• IPv4: 4294967296 (2^32)
• IPv6: 340282366920938463463374607431768211456 (2^128)

Then they simplyfied some things:

• Removed Broadcast in favor of Multicast and Anycast
• Added autoconfiguration without a DHCP server
• Better subnetting support

And much more

IPv6 traffic is globally steady at around 37%. So it isn’t a majority by far.

The perpetual chicken egg problem of IPv6: many users don’t have IPv6 because it’s not worth it because everything is reachable via IPv4 anyways because IPv6 only service don’t make sense because they will only reach a subset of users because many users don’t have IPv6…

Wenn man im Urlaub ist, bleibt man im Urlaub. Die Arbeit existiert nicht wenn ich Urlaub habe. Steht mir gesetzlich zu.

Es gab tatsächlich einen Vorschlag Gruppen zu machen die über mehr als eine Instanz laufen (FEP-2100 und FEP-d36d konnte ich finden). Es ist aber noch keiner angenommen und es hat auch niemand eingebaut.

Egal ob das Rechenzentrum brennt. Im Urlaub existiere ich nicht für die Arbeit und umgekehrt. Ich gehe da nicht ran.

Wenn der Urlaub beginnt hört die Arbeitsstelle temporär auf zu existieren. Du hast einen gesetzlichen Anspruch darauf im Urlaub nicht erreichbar zu sein.

Du hast recht aber bei Digital ist der Unterschied normalereise zwischen geht und geht nicht. Ein analoges Audiokabel kann die Qualität verändern indem es Frequenzen filtert.

Bei analogen Verbindung kann die Qualität was ausmachen. Bei HDMI oder ähnlichen natürlich nicht.

Mir ist auch schon aufgefallen, dass linke Bewegungen immer alle Probleme gleichzeitig behandeln wollen. Gerade bei den Demos gegen Rechts ist mir immer mal wieder aufgefallen, wie bestimmte Gruppen ihre Thema auch noch hinzufügen wollen. Das ist ein Problem wenn es leute abschreckt oder ausschließt. Es ist manchmal okay wenn man sich nur um ein linkes Thema kümmert.

Godmode: you maintain the fork.

Your phone is rawdogging all it’s connections. It can receive SMS and Phone calls without your intervention. There have been several zero-click bugs in the past that allowed injecting malicious code into your phone without any interaction.

There have been a few bugs in the past years that let you take over a phone without user interaction. There was one where you only need to receive an SMS (it was invisible even) and your phone is infected. Another one was a vulnerability in wifi calling and voice over lte.

A phone is not a passive device that only gets something when you request it. You take also it with you to public places, use it in open wifi networks and you get calls. All that while being used for security critical stuff like 2FA, banking and payment.

You shouldn’t use a phone without current security updates for much more than calling. It is a time bomb. If you want to educate yourself further you should look at “zero click vulnerabilities”.

Sometimes. It depends on the manufacturer. Some do more some don’t promise anything. You have to know what you have. Also the support time starts usually at the start of sale not at the time of purchase. That means if you buy a new phone that was released a year ago on clearance or something you might have only half the time.

Yes and no. For apple you can use their phones for quite a long time securely. For Android that is a very different story. As far as I know only Google with their new pixel phones and Samsung have offered more than 2 years of updates. After that time your phone becomes a security risk. So make sure your devices receives updates or can be used with a custom ROM (though that can be insecure as well).

I invented one for you:

Zungenspitzendilemma, das

When you have something stuck at the tip of your tongue, but looking it up feels like cheating.

Let me rephrase that: I never heard one. There is a word for tip of the tongue but not for the concrete situation OP described. I mean the possibility to just look up stuff wherever you are is a very recent development so it makes sense that a word that incorporates this isn’t invented yet.

There isn’t one in German.
