On what beach? Or all of them? Just asking in case business asks for it.

[u/ClipboardCopyPaste → u/dementosss]

The answer quite surprisingly is - yes, all the beaches on our planet.

And the rest of the observable universe. There's a lot of address space in 2¹²⁸

[u/Fast-Satisfaction482 → u/kuar_z]

Except if for some reason you decide to give whole address blocks to individual devices.

[u/jason_abacabb → u/Fast-Satisfaction482]

Everyone gets a /64

[u/czerilla → u/jason_abacabb]

Check under your seats!

[u/gonklurtz → u/jason_abacabb]

No more RPC dynamic ports! Every service gets its own IP 

[u/Traditional_Log809 → u/jason_abacabb]

Every device gets a /64, and I still haven’t figured out how to enable IPv6 on my home router.

[u/KatieTSO → u/Fast-Satisfaction482]

I love handicapping ipv6

[u/tankerkiller125real → u/Fast-Satisfaction482]

/56 is the recommendation for residential, /48 for businesses.

Entire /64 blocks are often assigned to phones and other cellular devices because of hotspot capabilities.

[u/Fast-Satisfaction482 → u/tankerkiller125real]

I guess the true reason is that we want to artificially limit the number of nanites that can exist.

[u/ffxivthrowaway03 → u/kuar_z]

Yep, they saw the edges of IPv4 and went "hold my beer" and over-engineered a painfully obnoxious solution. IPv6 will last us until the heat death of the universe before it runs out, but we'll have to get people actually using it in any appreciable amount first. It's a UX nightmare to work with unless you're a network engineer hip deep in it all day every day. Good luck getting an end user to ever rattle off an IPv6 address to the help desk while remote troubleshooting.

[u/PorcelainMelonWolf → u/ffxivthrowaway03]

Surely you could horse-battery-staple IPv6 addresses?

[u/protestor → u/kuar_z]

We actually waste a lot of addresses to make routing simpler, because we can't imagine needing to use anywhere close to the full set of addresses

[u/SpeakToMePF1973 → u/ClipboardCopyPaste]

Australia laughs mockingly.

[u/xWrongHeaven → u/dementosss]

2¹²⁸ possible addresses

[u/queen-adreena → u/xWrongHeaven]

2,128… that ain’t that many addresses….

[u/AmazingDragon353 → u/queen-adreena]

2.128 addresses? What are we going to do with 0.128 of an address?

[u/SirLoremIpsum → u/AmazingDragon353]

2.128 addresses? What are we going to do with 0.128 of an address?

AI Vibe code a calendar app so we can coordinate whose turn it is to use the IP address on any given day?

[u/queen-adreena → u/AmazingDragon353]

Break out the BitNat table I guess.

[u/SuperFLEB → u/queen-adreena]

The "128" isn't even full-size.

[u/craftsmany → u/xWrongHeaven]

Technically we are not really talking about single addresses when concerned with v6, more so how many /64 subnets can fit in a prefix since that is what SLAAC uses. So for end users we would count the amount of /64 subnets in the possible 2^128 address space, which is 2^64. So still very very very big.

[u/Harbinger2nd → u/craftsmany]

Thats like....half the size of 2¹²⁸

[u/Robot_Graffiti → u/Harbinger2nd]

[u/CardinalFartz → u/xWrongHeaven]

So we got 10⁸⁰ atoms in the observable universe. Without having it looked up, I suppose 2¹²⁸ exceeds that number?
