I guess that works for most people except gamers and people who get rate limited because of the actions of others.
Article is correct, IPv4 didn’t die hard.
It doubles the workload and knowledge required, doubles the security attack surface, and because of the 2nd part, doubles the security risk.
Right or wrong that's the calculation for most spots.
Did it for a decade, and that's news to me.
At my house I've had SSH open to the V6 internet for 8 years and have the logger set up to email me for any connections, and I have never once seen an attempt that wasn't me. For popular sites with well known DNS names that's obviously different, but I keep DNS current and can SSH by name to that V6 listener from anywhere so it's not my ISP trying to save me from myself either. And that's not even a host with the normal automatic temporary addresses, it's been a fixed interface id portion with an effectively static V6 prefix for years.
For a while I had several other services open as well, at one point we even played around with using NFS and iSCSI over IPv6 on the internet just for giggles, no actual important data. I can imagine some sysadmin's face twisting in horror just reading that knowing the carnage that would have ensued doing that with V4, where we commonly drop entire geo-blocks just to curtail the log spam of all the various automatic admin portal and VPN login scans.
There are of course techniques to gather live V6 addresses but between the vast space and temporary addresses on most end-user devices it really has been a night and day difference.
And when they do give you v6 its a /64.
I wish there might be a category of prosumer friendly ISP of sorts. Those exist but they are hard to find.
You create an SSH reverse tunnel (-R option) from a server in your home network to your remote VPS. This gives you a localhost port on your VPS to your server SSH port. Something like:
ssh -NT -R 2222:localhost:22 vpsuser@yourvps.com
ssh -J vpsuser@yourvps.com:2222 homeuser@yourhome.com
They've built such an incredible product I actually feel guilty I pay absolutely nothing for it.
Personally I don't think IPv6 will ever supplant IPv4. As far as big tech is concerned, NAT solves the problem well enough for clients and SNI routing solves it well enough for servers.
What incentive do they have to make things better for small orgs and p2p use cases? Better from their perspective to retain control over IPv4 real estate and extract rent.
I'm not sure why you guys keep saying IPv6 won't happen, when it's already happened. Just ostriching, or incentivized to keep IPv4 address prices high, or what gives?
Far more important than current adoption is rate of adoption, which is slowing.
US mandates will certainly help and may be enough, but the US can't force other countries to follow. Many countries have far lower adoption rates.
If it can't upgrade in time, it might remain connected using some kind of translator or proxy. Even if not official, someone would surely run one - it's too useful and we're not talking about a censorship scenario where it would be illegal. Experience shows this is very annoying and will quickly be upgraded to native level. Note that tunneling is native.
Most end-user ISPs today use some kind of tunneling to separate the architecture of their network from the architecture of the services they deliver to customers. If you use DSL, your connection is (usually) a PPPoAoE tunnel with one endpoint at your house and another endpoint at one of your ISP's POPs - the entire access network feels transparent to you. If you use a cellular network, it does something similar with GTP.
And considering that fact, it's not as hard to upgrade a network to IPv6 as you might think. Some core routers and edge routers must be upgraded, but the majority of the network is tunneled over. Perhaps during a transitionary period, your CPE (home router) will encapsulate your IPv6 packets in IPv4. This doesn't require a new router because most of them do routing in software and can just get a firmware update.

Maybe the 2000s, yes. This experience in the 90s was reserved for businesses and schools that could afford a T-carrier connection. The rest of us had dialup.
