Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

I'm convinced it hasn't taken off because they're too complicated for the human brain to easily reference. Four triplets is simple enough.
All the shortening rules trip me up. I'd much rather work with addresses with standardized number of hextets and ideally the same number of digits than not have to type a few zeros.
all of these are the same address: 2041:0000:0001:0000:0000:0000:875B:131B 2041:0000:0001::875B:131B 2041:0:0001::875B:131B 2041:0000:1:0000:0000:0000:875B:131B 2041::0001:0000:0000:0000:875B:131B 2041::1:0000:0000:0000:875B:131B 2041::0001:0:0:0:875B:131B 2041:0:1::875B:131B 2041:0:1:0:0:0:875B:131B 2041:0000:1:0000:0000:0000:875B:131B 2041:0000:01:000:00:0:875B:131B 2041:00:1::0:875B:131B
Ugh. Yes.
The fact that they have shortening rules already shows it's too complicated.
They would've been better off with a shorter length, and ditching hex for a base 32 string.
Imo they should have kept the ipv4 format but instead of maxing out at 255.255.255.255 make it 65535.65535.65535.65535 this aproach makes the address pool more than 4000000000 times larger and is backward compatible with ipv4 so it could be a drop in replacement for most things. And if we ever do end up running out of over quintilion (18446744073709551616) ips we can just keep going up, to 4294967295.4294967295.4294967295.4294967295.
What's the problem?
Once you learn IPv6 it isn't bad. I would highly recommend that you check out onemarcfifty IPv6 videos
True that. They're also less recognizable as an ip address. They don't stand out
It really isn't all that complicated. Honestly in some ways it is easier since you don't need to worry about subnetting. Also SLAAC is pretty cool.
The key to IPv6 is to not apply your IPv4 brain to it. It works very differently and in some ways it is better.
Since I am behind CG NAT I try to use IPv6 for most things at home. It works pretty well most of the time. Also a lot of Software (or should I say games) that claim to not support ipv6 do, as long as you can give them a domain that only has AAAA entries...
SLAAC is pretty cool if it works and if you can weed out all the devices with privacy extensions enabled by default, so you can properly apply rules...
That's what DNS is for.
Well, yes, for users. But I'm in tech. And it's the tech people that need to implement it. And when I'm trying to hunt down why something about DNS or a firewall rule isn't working, I really don't want to be juggling gigantic alphanumeric strings.
DNS doesn't work over IPv6 since it doesn't allow fragmentation
