Sometimes you can get therapy covered through health insurance. It’s worth checking, because therapy can be really helpful, even just for having someone to share stresses with. I hope you’re able to find someone!
My university is still mostly on IPv4 for our infrastructure. We got in early on the IPv4 address gold rush, so we got a full /16 block. Not quite MIT’s 18.0.0.0/8 block, but enough so there’s little pressure to move. It can be a little embarrassing, feeling like an institution that should be breaking ground is instead trailing behind. At the same time, our IT department is chronically understaffed, so I can understand not doing the switch. It’s not as simple as just flipping a switch, there are many ramifications of IPv6 that aren’t immediately obvious.
There's literally nothing stopping a moderately skilled IT team from integrating ipv6. You can run any site easily using both. The exceptions are few and even those aren't that hard to deal with.
Source: been running dual ipv4/ipv6 Web servers for over 10 years (maybe 15 would need to check) . Likewise had ipv6 dual stack at home for a similar amount of time, initially using tunnels and then native.
Almost every server provider will give you ipv6 for free. There's really no excuse these days not to run your services on both protocols now.
The worst gotchas and limitations I have seen building my own self-host stack with ipv6 in mind has been individual support by bespoke projects more so system infrastructure. As soon as you get into containerized environments, things can get difficult. Podman has been a pain point with networking and ipv6, though newer versions have become more manageable. The most problems I have seen is dealing with various OCI containers and their subpar implementations of ipv6 support.
You’d think with how long ipv6 has been around, we’d see better adoption from container maintainers, but I suppose the existence of ipv6 in a world originally built on ipv4 is a similar issue of adoption likewise to Linux and Windows as a workstation. Ultimately, if self-rolling everything in your network stack down to the servers, ipv6 is easy to integrate. The more one offloads in the setup to preconfigured and/or specialized tools, the more I have seen ipv6 support fall to the wayside, at least in terms of software.
Not to mention hardware support and networking capabilities provided by an ISP. My current residential ISP only provides ipv4 behind cgnat to the consumer. To even test my services on ipv6, I need to run a VPN connection tunneling ipv6 traffic to an endpoint beyond my ISP.
I'm lucky that I have a choice of multiple ISPs all offering service on gigabit symmetric fibre. I've managed to keep my old setup of a /29 IPv4 allocation and /48 IPv6 allocation. But before IPv6 was available, I used tunnels at the point of the router with no problem. As such, the internal network doesn't need to know there's a tunnel and gets native IPv6.
Yes, and it is the correct number of zeros to use. I find it helps to put things into scope. “Trillion” is an abstract magnitude to most people. Writing it out numerically makes it clear how absolutely enormous the number is.
Worth pointing out that credit scores are completely detached from the government. They are entirely private industry, that is collecting and selling your financial info without your consent or opt in. If you were born before 2004, then they have also accidentally leaked literally all your personal info to the dark web, with literally 0 consequences.
Credit scores require you to get some kind of debt. This is because it’s not a score of your financial health. It’s a score of how reliably you repay your debt.
I know very little about ipv6, but CGNAT is Carrier Grade Network Address Translation.
NAT (Network Address Translation) is how your home router takes your one public IP address and is able to simultaneously allow your phone, your PlayStation, and your smart fridge use the internet.
CGNAT is basically the same thing expect on a much larger scale and controlled by you ISP.
IP addresses ran out, IPv6 adds more addresses than we may need, ISPs decide to take away the user’s ability to host servers (more or less (more less than more)) rather than upgrading the infrastructure
There is IPv4, it’s an internet address that points to a specific computer, or at least it’s supposed to. IPv4 supports up to 4294967296 addresses, which might seem like a lot until you realize how many devices are connected to the internet. Almost the entire IPv4 range is full, and ISPs have resorted to letting 1 IP point to multiple computers also known as NAT. It’s what your router does, and why your laptop and phone all connect to the internet using your routers’ IP address. Carrier Grade NAT takes it one step further and allows hundreds or more home networks to connect from a single IP address.
CGNAT kind of sucks because you can’t run servers behind them because it doesn’t know which of the hundreds of computer traffic has to go to. IPv6 would solve this entire mess, but ISP’s won’t invest in it because they don’t want to spend the money and just delay the inevitable until they have to.
**True ELI5:**We ran out of signs for house numbers and instead of getting new ones we started giving everyone in a street the same house number
Thank you. So in a way if the carriers upgrade their infrastructure there would be a decrease in privacy because then it’s a one-to-one correspondence between IP address and customer, but then the customer would have the ability to host servers? The one scenario where the industry dragging their heels on upgrading is actually good for the consumer (in some respects) lol
Adding commas to that number: 4,294,967,296 addresses. More humans that IP address seems like a huge miscalculation in the internet infrastructure
Who could’ve thought in 1981 that more than a few thosand universities would ever like to connect to the then 250 machines big ARPANET. With 4 billion addresses, there was plenty of headroom at the time.
In 50 years, when the last ISP finally switches to IPv6, we’ll be wondering how short sighted we were as now every pencil has an IP address in the interplanetary compu-global-hyper-meganet.
We planned for that. We should be fine at least until we are an interstellar species. We could assign an IPV6 address to EVERY ATOM ON THE SURFACE OF THE EARTH, and still have enough addresses left to do another 100+ earths. It isn’t remotely likely that we’ll run out of IPV6 addresses at any time in the future.
It’s a bit more complicated than that. Governments still spy on an IPv4 address, but because that address is shared, it’s spying on everyone behind it. At least with IPv6, it’d be targeted.
Goverments (depending on juristiction) have laws requiering isp’s to keep track of cgnat port combos. So not only is there no privacy from ipv4 cgnat. Now the isp must also spend a lot of money on the nat state tracking database.
If you need that kind of privacy, use a vpn and the tor onion network.
Usually the NAT is at home in the router and every customer has their own IPv4 address. NAT at the ISP means several customers share an IPv4 address. If the authorities are now investigating the activities of an IPv4 address, it is difficult to say which customer it was because multiple of them shared the IP address.
I tried an IPv6 AWS Lightsail instance recently. It had a private IPv4 address, but it’s not behind NAT and won’t route outside the network.
Which would be fine if all the software packages you need can access things over IPv6 on their servers. One that doesn’t is WordPress, because of course it doesn’t. That means no plugins or updates except by manual downloads.
But hey, who would ever want to run WordPress on a cheap Lightsail instance?
