These days, your ISP would (hopefully) give you at least a whole (static) /56, so you can always reserve some prefixes for your not-really-home networks ? http

I have a static ip4 address, but were that not the case yes I'd take the ip6 plunge. Edit: Which I could do as my ISP and mobile network both support ip6. Y'all need better ISPs :D

  > Y'all need better ISPs :D If only there was one around here, but alas, they're all basically the same 2-3 ISPs - a couple of main ISPs, then smaller ones who are just using their network and renting bandwidth.

Hahahahaha your ISP supports IPv6 already?
- rglullis 5y ago
  What you mean already? In Europe it has been for at least a decade. Even in Brazil v6 has been standard since 2014 or so...
  - mort96 5y ago
    I'm in Europe, I have yet to have used a residential (or even corporate!) network which has any form of IPv6 support. Of all the networks I've interacted with over the years, only my cell carrier supports IPv6.
    - rglullis 5y ago
      Ok, at least in Germany I noticed since I moved here that all residential routers were dual-stack. I even ended up disabling v6 because I wanted to run some things in my home network and I wasn't too sure about the firewall configuration.

        Germany is one of the better countries when it comes to IPv6 adoption, and even then it's only about ~55% https://www.google.com/intl/en/ipv6/statistics.html https://www.google.com/intl/en/ipv6/statistics.html
      - BlueTemplar 5y ago
        Something that I find incredible, but have seen no one contradicting yet, is how when ISPs have started to roll residential IPv6 by default some years ago, they first had no firewall on IPv6 and/or later it was disabled by default (so only few % of users would enable it at best). (Not sure if the situation has changed ?) Now, IPv6 (when properly implemented, which is another failure mode) comes with much better safety out of the box (like not being able to scan all the suffixes in a reasonable amount of time to find computers on the local network to target), but I'm still impressed that now we seemingly have hundreds of millions of personal computers "directly" connected to the Internet with at best only the OS firewall as protection (when one exists), and it hasn't resulted in major hacking issues ! (yet.)

        The difference is a direct IPv6 conmected Windows 7-11 is actually prepared to be on the internet in a way that Windows 95 never was. There never really was any such thing as a safe network, but it used to be acceptable to assume LAN traffic was safe. Now we know you might be on airport wifi or a large corporate network with compromised systems and the OS and systems software needs to handle that.

    Dont hold Europe up like a shining beacon.. It's a coin toss on if BT will properly allow ipv6 traffic each time the router reboots. I've had to make provisions to force ipv4 on my machines because although composer et al. runs fine on my vps and elsewhere, if it tries to access it via ipv6 at home it more often than not hangs indefinitely.

    "In Europe"? Europe is made of many countries and all ISPs have a national structure (even if they operate in several countries) and they all decide to roll out or not ipv6 independently.
    - rglullis 5y ago
      My bad. I forgot that one of the many issues I have with the EU includes the fact that it is also Big Telco's little bitch, and they only institute block-level policies when it suits Deutsche Telekom/Vodafone/Telefonica.
      - naoqj 5y ago
        I don't understand. Are you suggesting that the EU should mandate telcos to provide users with ipv6? Why? And who is going to pay for that? Telcos will just push the price to the end users. I don't need ipv6.
        rglullis 5y ago
        Pushing IPv6 would more likely than not decrease the cost for end users, and it could allow competition from independent ISPs.
        dangerface 5y ago
        In the uk we already pay bt tax money to keep our network up to date ipv6 should be included in that. Most people want ipv6 so they can get more ips / static ips, but from a legislation perspective its more about future proofing and staying relevant.
        naoqj 5y ago
        Most people want ipv6? What % of people even know what ipv6 is?

  Comcast in the US does (if you use your own router and configure it correctly.) There's this goofy band of people that know just enough to bring their own router but don't understand why a misconfigured AAAA record can mess up the happy eyeballs algorithm and are convinced Comcast is "censoring" small business. It's funny and kind of sad to read comments from people who are certain their misconfigured networks are the result of some "international conspiracy" against them. That's probably why Comcast has it turned off on the routers they loan to customers.
  - BlueTemplar 5y ago
    Yeah, that has been typically the case a few years ago around here - you could have more than a single /64 on a residential connection (and better than the bare minimum of other IPv6 functionality), but it required to get your own router (and sometimes even spend time with tech support because they wouldn't test that use case as much as their own router that you'd get by default).
  - johnvaluk 5y ago
    Comcast Business requires customers to use a gateway provided by Comcast to support static IP addresses. I was thrilled to finally get IPv6 support, but it seemed impossible to prevent Comcast from inserting their own nameserver in IPv6 leases, which broke my network. I tried running my own dhcpdv6 and radvd servers to no avail. This took me way out of my comfort zone and much deeper into the weeds of IPv6 than I ever expected to go. I finally disabled IPv6 (and I can't even tell you how I did it) to get things working properly again. Maybe I don't have the required skillset to implement IPv6 properly, but I really got the feeling that Comcast introduces unnecessary obstacles for business customers with slightly advanced needs in order to serve the lowest common denominator (aside from my special requirements, IPv6 mostly worked out of the box, which is probably their goal).
    - xoa 5y ago
      Seconding this. It's a very irritating implementation detail of Comcast Business service. It can be worked around of course, if you have a VPS somewhere close-ish with a static IP you can do the whole WireGuard tunnel thing at the cost of some extra moving parts and maybe a minor latency hit. And while overall their business offering is certainly vastly better than their consumer shit, if you're on their router they're still jerks. I've noticed their own pushed WiFi keeps switching itself back on for example. Overall it reinforced my desire to use absolutely anything but Comcast whenever possible, though when it's not I'd still pick business service of consumer service.

    In many parts of the world it's no IPv6 on mobile, just CGNAT with probably thousands of customers sharing one ip.
