IPv6 has temporary IPs for privacy reasons. NAT is NOT a firewall. Setting up a real firewall is more secure and gives you more control without things like UPNP and NAT-PMP.

I still have my IPv6 sage shirt somewhere.

You should rather find out why things break with IPv6. The best time to make IPv6 work is now.

Why should I use IP6 in my small home network?

• No NAT. Especially in a home network NAT can be a hassle.
• A bit more anonymity through changing temporary adresses.
• Some people don’t even have a real IPv4 address anymore in their home and only connect through CGNAT. That means that if you disable IPv6 on your computer you only use CGNAT.
• The fact that EVERYONE needs to transition to IPv6 or it doesn’t make sense.

Or in an SMB where there are less than 100 IP’s used on a daily basis?

• No NAT. NAT is no firewall. If you can’t set up a firewall you are honetly not qualified to be a network admin.
• Easier VPN S2S-VPN. I had a few instances where the internal IP ranges clashed.
• All the other advancements of IPv6
• The fact that EVERYONE needs to transition to IPv6 or it doesn’t make sense.

First I have to pay the cost of transition, along with the risk of things not working while I do this, and then the risk of something new being added and not working.

You can transition step by step. Dual Stack is a thing.

IP6 is good for backbone right now. It will slowly transition into LAN for larger environments (think Enterprise when they setup new network segments, since they’re buying new hardware anyway. But only after extensive testing.

That makes no sense to me. Every network in itself doesn’t need IPv6. The 10.0.0.0/8 range has 16 777 216 addresses. IPv6 only makes sense if everyone uses it. We bought ourselves time with NAT and CGNAT and splitting up older ranges but that won’t last forever and is costly.

Everyone needs to transition otherwise services will need to keep their IPv4 forever. And if the services keep their IPv4 users don’t have an incentive. Maybe we should transition BEFORE there is time pressure. Now is the time to slowly start setting everything up with enough time to plan and test firewall rules and appliances and everything else.

IPv6 after so many years still is a victim of the chicken-egg-problem. People don’t need it because services don’t support it because people don’t need it because … and so on and so forth. I try to enable IPv6 wherever I can and I didn’t have a propblem for ages. Dual stack is stable and there are actually a good amount of services that support it.

I think we should all push to implement IPv6 so that IPv4 can finally be laid to rest. Using IPv4 makes everything a bit more expensive because it is so damn expensive to get a stupid number. If someone is really scared that every computer has a publicly routable IP, and if you really think you can not configure a firewall, there is a private IPv6 space and you can use NAT with IPv6. It’s not recomended but it’s possible. I’d still say using a firewall is not harder and just as safe.

And there is the fact that you can make so many subnets which can make your internal network so much safer. You can controll better how packages are sent to groups because broadcast was dropped in favor of multicast. There is IPSec Support built in. Secure Neighbor Desicorvery to prevent attacks like ARP spoofing. There are a lot of reasons to implement IPv6 and even to switch to IPv6 only if possible.

I’d consider btrfs if they finally make their raid5/6 implementation stable. I want to work with multiple disks without sacrificing half of my storage.

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.

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).

But I want something else.

This one might save power because it will only dry as long as it needs to.

The ActivityPub protocol works by sending out every action on one server to any subscribed server. The subscribed servers save this data and make it available to the local users. If it worked the way you described, every server on the fediverse would store all the data from the whole fediverse. That seems wasteful.
