I’m in the ARIN region. Two things:<p>1. My home has Verizon fiber. No native IPv6. I have a tunnel for this, but such solutions aren’t going to work for the masses. The other in-region residential provider, Comcast, has great native IPv6 service, but had layer 2 performance issues versus price.<p>2. At $dayjob I just ordered a circuit from Level3/Centurylink for a branch site. No IP justification form was required if I needed only IPv4 /30. But for dual IPv4 /30 + IPv6 /126, I was required to provide written justification. Shouldn’t this be the other way around? Unencumbered IPv6 for all, with paperwork for IPv4?<p>EDIT: these are not site allocations, just point-to-point link addresses, hence the /126. Still, I’m being asked to justify IPv6 but not IPv4.
There are five regional internet registries (RIRs), and Ripe NCC is one of them. Here's a map of which services what region[0]<p>Does this mean we've finally run out of new allocatable IPv4 addresses with the RIRs?<p>[0]: <a href="https://en.wikipedia.org/wiki/Regional_Internet_registry#/media/File:Regional_Internet_Registries_world_map.svg" rel="nofollow">https://en.wikipedia.org/wiki/Regional_Internet_registry#/me...</a>

We ran out of IPv4 addresses again. How many times has this happened this past decade?<p><a href="https://news.ycombinator.com/item?id=2174992" rel="nofollow">https://news.ycombinator.com/item?id=2174992</a> 9y<p><a href="https://news.ycombinator.com/item?id=4480532" rel="nofollow">https://news.ycombinator.com/item?id=4480532</a> 7y<p>Looking forward to the next time we run out of IPv4 addresses.
Ripe NCC has run out of address it will give for almost nothing.<p>I checked, and IPv4 address price is somewhere between $20 and $30[0]. It's not so bad given it's a one-time buy - and using cloud services de facto creates a situation where the buying is in bulk.<p>The real shortage will start be when prices reach $170 I guess? Should take a few years...<p>[0] <a href="https://ipv4marketgroup.com/broker-services/buy/" rel="nofollow">https://ipv4marketgroup.com/broker-services/buy/</a>
My ISP-provided router supports IPv6, but I've disabled it because I don't feel like setting up a firewall for all those poor devices on my network.<p>Are there any guides for how to properly secure a home network so that I can re-enable IPv6 with a clear conscience?
I hope all home provision moves to CGNAT IPv4; IPV6 are too easy to track, and every ISP that I've seen ties the prefix to the customer.<p>Who cares about cookies, 1st party or 3rd party, when you have a unique ~60 bit per customer identifier?<p>My ISP gives un-natted IPv4, but I get a different one each time I reboot the modem, which I do every now and then.
I wished IPv6 could be memorized. I can rattle the addresses of all the devices in my home network off with ease, but have trouble remembering a single IPv6. The "just use DNS" answer isn't a good one; stuff sometimes breaks, and it's much harder to fix when I've got to look everything up.
I'm in Slovakia. The IPv6 adoption is below 1% and the ISPs don't plan IPv6 rollout because "We have enough IPv4 addresses.". Nowhere I ever had native IPv6 available on home connection, it is option only to business clients.
This will lead to ipv6-only services pretty soon. As the cost of ipv4 space gets higher and higher you'll see things like VPSes and cloud hosting stop offering a free IP with their services, and eventually businesses will stop using it too.
How many ipv4 are in poss2of the US Gov and military? Do they really need all of those?<p>With all these elastic search instances running open to the public I have the feeling that with IPv6 this will get worse as NAT no longer protects you.
Typical of humanity's poor prioritization algorithm, I submitted on this 88 days ago … and got zero comments <whomp_whaa>.<p>But, now that <i>it's happened</i> … it shoots to the top story.<p>For anyone interested, the blog post from RIPE that I submitted is still up, here:

Time to shut down the Internet and go outside.<p>So why are IPv4 addresses so valuable? Mostly because IPv6 is overly-complicated and a pain to work with. We should have first added a new range where 5 of the 8 hextets were 0000. And found a simple way to write it without ::<p>Why wasn't that done?
Technical arguments aside; IPv6 is just "advanced" enough to allow corporations to fuck over the last bastions of free internet and turn it into nothing but tightly controlled broadcast TV 2.0.<p>The road to hell is paved with good intentions so I guess I will see you all in hell.
Is IPv4 shortage really going to be a problem?<p>For client use, carrier-grade NATs allows to have 1000 IPs per customer, giving 6 million addresses.<p>For server use, TLS SNI allows to have one IP per datacenter, which are estimated to be around 10 million in the world.<p>Non-TLS inbound usage is probably relatively rare, so overall around 100 million addresses should be fundamentally enough even accounting growth.<p>Of course there's a lot of inefficiencies, but the fundamentals seem to say that the IPv4 address space is enough.
