/64

That's not an address, that's a whole fucking subnet consisting of 2^64 different addresses. ☝️🤓

[-] LaggyKar@programming.dev 32 points 8 months ago* (last edited 8 months ago)

It is a single address with an associated subnet mask, indicating what subnet the address is in.

The subnet would be 3fff:a1:1ab:bc67::/64, for the top one.

I'll see you in court.

[-] Lyra_Lycan 16 points 8 months ago

Maybe but I always have to enter /24 after setting a VM's manual IP for it to be valid

[-] Kazumara@discuss.tchncs.de 8 points 8 months ago

That would depend on the network environment. If your VM is on a /28 subnet and you set /24 it won't be valid

[-] ikoz@programming.dev 39 points 8 months ago

There was a cool project that converted hexadecimal numbers (or IPs) to pronouceable words. I think it was also more dense, and of course faster to say / easier to remember.

Perhaps organised into some sort of domains for clarity?

[-] comfy@lemmy.ml 14 points 8 months ago

Just make your IP addresses pronouncable words like feed:deaf:babe:beef:cafe:: problem solved ez (working 2023!)

[-] some_kind_of_guy@lemmy.world 3 points 8 months ago

But you're limited to a-f. I wonder if anyone's figured out how many addresses are actually possible with that system.

[-] JargonWagon@lemmy.world 4 points 8 months ago

throw some 1337 speek in there and you're all set!

[-] Ghoelian@lemmy.dbzer0.com 2 points 8 months ago* (last edited 8 months ago)

I think that's just 6^32, no? (Amount of options^string length). Which is 7958661109E24.

[-] some_kind_of_guy@lemmy.world 3 points 8 months ago* (last edited 8 months ago)

Yeah, calculation of the amount of possible strings containing only a-f is trivial. But the idea is for addresses to be memorable. So I'm wondering how many strings which are valid IPv6 addresses are possible if you are limited to actual English (or, pick a language) 4-letter words containing only a-f. As someone mentioned, this could be expanded with 1337-speak.

[-] Ghoelian@lemmy.dbzer0.com 1 points 8 months ago

Ahh right, that would be a bit more difficult to calculate.

I guess you could make a script which just bruteforces all combinations of a-f against an English dictionary. I might try to do that tonight.

[-] LaLuzDelSol@lemmy.world 9 points 8 months ago

That's cool, but I'm sure it broke the relationship between ip addresses. Like it would be hard to tell if 1 IP was 1 higher or lower than another/ in the same /28 subnet, etc

[-] eager_eagle@lemmy.world 5 points 8 months ago* (last edited 8 months ago)

maybe they could be sorted alphabetically to give you an idea, but yeah, it'd be harder to know for sure without a mixed format like

worda:wordb::f1

[-] relativestranger@feddit.nl 4 points 8 months ago

there's no place like Nyamyochu Sha

[-] slazer2au@lemmy.world 33 points 8 months ago

Yes, who do you think deployed it.

[-] drkt@scribe.disroot.org 15 points 8 months ago

The future is now, old man

[-] AVincentInSpace@pawb.social 10 points 8 months ago

ipv6 is strictly superior and i will die on this hill

[-] Ladislawgrowlo@lemy.lol 2 points 8 months ago

We need to ban ipv4, ipv6 networks only

[-] aliser@lemmy.world 7 points 8 months ago

I don't get how regular network works, ipv6 is like 10 times more confusing with all its prefixes and subnets

[-] purplemonkeymad@programming.dev 7 points 8 months ago

I mean they dropped the parts of ip4 that are not used. They only multiplied the number of bits by 4, otherwise it's the exact same ideas. The confusing part might be that a device gets multiple addresses off the bat. Using decimal for 128 bits would have made the address even worse.

  • 3fff:a1:1ab:bc67::63c6:4fa4:40a:9aab/64
  • 2001:db8:a1ab:34ac:67ab:4af3:49a:5bb3/64
  • 3fff:d7a:cafe:77:9952:dc4d:da41:e1d7/64

I was bored. And need to train ipv6 typing skills.
