Re: Update: Approaching IPv4 Run-out
#92What's going on with IPv6 that is preventing it from alleviating the IPv4 scarcity?
We're an IT firm.
My boss: "why in the world would I figure out and enable ipv6 and have to configure everything twice and have twice the attack surface?"
Me: "umm... so that maybe 30 years in the future we can switch v4 off?"
It's a tough sell, even in IT :/ imo we should just plan time to do things properly instead of holding adoption back.

#93Earlier quoted context omitted.
I always thought that basically the only difference between IPv4 and IPv6 is the number of bytes in an address. Lately I've been learning a lot more about IPv6 and there are a TON of subtle differences in the protocols that matter if you're operating a large network. Random example I recently read about: the way link-local addresses are generated. [0] Not that this excuses inaction, but it does give me more empathy f…
What happened is they changed a bunch of things about the protocol because they thought it would be a very forced adoption. Instead, it caused lagging adoption because of all the changes. If IPv6 was just IPv4 with extra addresses, the adoption rate would have been very quick.
On the other hand, you really do not get many chances to re-architect a universally used network protocol. It's important to make changes with a long-lasting impact.

#94I wonder if they will implement some kind of clawback for orgs that are sitting on large chunks of sparsely used blocks. Old tech companies and colleges come to mind. https://myip.ms/info/ip_ranges_blocks/Major_Biggest_IP_Addre...
When the options are: let them profit awkwardly from a windfall, claw it back against their will, or make their IPv4 assets obsolete, focusing on the latter seems most productive. The UK’s largest mobile provider now gives me an IPv6 only connection and I didn’t even notice.
And yet one of the largest UK ISP's by customer count (Virgin Media) still haven't managed to roll out DS-LITE ... 6 years after announcing it.

#96How does this apply to email delivery? The biggest factor is having a "clean" IP address. Do these eventually become prohibitively expensive? Does email protocols switch to IPv6 and stop considering address reputation?
With email deliverability the key factor is now domain name reputation and less ip.
I never considered that it could be that way. That would be really nice: new domain, new reputation. Domains cost money, so that's good against spammers in general. And it's good for me, because my domains never sent any spam.
But alas, no, that's not the state of things.

#97IPv4 runout can be be pushed far into the future with DNS SRV records. This is a preventable emergency. Why it hasn't be included in HTTP/2|3 is mind boggling.

Personally I like the link local addresses, SLAAC, and NDP features.

Apple have made it a hard requirement for apps to operate correctly on IPv6-only connections for a few years now. If your app doesn't work unless it's on IPv4, Apple will reject it.
That can't be totally true, Twitter doesn't work on v6.

#100We're still waiting for the processing of our application from beginning of September, I hope we can still get at least a /24 block. We mainly plan to use it to become independent of specific cloud / IT providers and control more of our infrastructure stack.
I'm not sure in what business area you are, but aren't domain names usually enough to abstract resolution from location?
Not if you want to do things like E-Mail or provide stable IPs to customers. Also you'll get a more direct uplink and have more control over what traffic goes in or out (since you can blackhole traffic yourself).
