Welcome to the Unpopular Opinion community!
How voting works:
Vote the opposite of the norm.
If you agree that the opinion is unpopular give it an arrow up. If it's something that's widely accepted, give it an arrow down.
Guidelines:
Tag your post, if possible (not required)
- If your post is a "General" unpopular opinion, start the subject with [GENERAL].
- If it is a Lemmy-specific unpopular opinion, start it with [LEMMY].
Rules:
1. NO POLITICS
Politics is everywhere. Let's make this about [general] and [lemmy] - specific topics, and keep politics out of it.
2. Be civil.
Disagreements happen, but that doesn’t provide the right to personally attack others. No racism/sexism/bigotry.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Shitposts and memes are allowed but...
Only until they prove to be a problem. They can and will be removed at moderator discretion.
5. No trolling.
This shouldn't need an explanation. If your post or comment is made just to get a rise with no real value, it will be removed. You do this too often, you will get a vacation to touch grass, away from this community for 1 or more days. Repeat offenses will result in a perma-ban.
Instance-wide rules always apply. https://legal.lemmy.world/tos/

This is the worst math that ever mathed. IPv4 is 32 bits of address space. IPv6 is 128. That is 2^32 vs 2^128. Not 2^52, which isn’t even wrong it’s just weird, hopefully this is just some weird performance joke. There are enough addresses in ipv6 to address every known atom on earth. We aren’t running out anytime soon. 96 doublings of IPv4s address space is a number you can’t fathom.
That wasn't what I said. 2^56 was NOT a reference to bits, but to how many IPs we could assign every visible star, if it weren't for subnet limitations. IPv6 isn't classless like IPv4. There will be a lot of wasted/unrunused/unroutable addresses due to the reserved 64-bits.
The problem isn't the number of addresses, but the number of allocations. Our smallest allocation, today, for a 128-bit address: is only 48-bits. Allocation-wise, we effectively only have 48-bits of allocations, not 128. To run out like with IPv6 , we only need to assign 48-bits of networks, rather than the 24-bits for IPv4. Go read up on how ARIN/RIPE/APNIC allocate IPs. It's pretty wasteful.
