I'm still waiting for Hetzner to support servers (physical and virtual) without public IPv4 addresses. I could easily free up the ~50 public addresses I'm using. One public IP will do, I can reverse proxy everything else. But there's no support for that. So every time I spin up a 1 vCPU tiny VM, which will never connect to the public internet, I'm wasting an expensive resource. Sorry.

This! I don't see any reason for _internal infra_ to use IPv4, if it's under your control. At least AWS lets you have "private" IPv4's only. (Dunno about the situation with GCP or Azure, happy to learn about that.) But I'd gladly set up my stuff in IPv6 and expose only the endpoints in IPv4.

  Unfortunately the mantra of "ain't broke, don't fix" is law at some companies. Pushing IPv6 will be met with immediate resistance because it brings no benefits but does add the risk of something not supporting it yet.

I wish you could have your own IPv4 subnet with your VPC, like at home, with 192.168 etc

  You can; Hetzner Cloud has private networks.
  - elric 5y ago
    Well, yes, but in addition to that each instance also has a public IP.

Kind of unrelated, but ~50 public addressed, do you have a serious production environment on Hetzner? If so is it pretty reliable? Considering using.

  Hetzner is great: professional, high quality, and cheap, cheap, cheap. Their margins are low, however, so I understand it is possible to get fired as a customer if your support burden is too high and your ROI goes negative, so be on your best behavior to keep access to those prices.

    +1, it's been very reliable (have between 50-100 VM's there).

    > I understand it is possible to get fired as a customer if your support burden is too high and your ROI goes negative, so be on your best behavior to keep access to those prices. That's not a nice statement. It sounds like Hetzner will cancel your contract as soon as you submit a support request, which is not true (I personally opened in ~May 5-10 tickets within a few days when trying to boot from UEFI). I really do not think that they track single customers in relation to their single ROIs.

        It still gave some weird impression that contract canceling is something that hapens usually.

Yeah, me too. Was confused why they needed to have an IP at the beginning, coming from AWS, since they have internal networking now. The public IP doesn't serve any purpose for me, and would perhaps also improve security.

If you are willing to go ipv6-only on Vultr.com it brings the price of their smallest virtual-server option down to $2.50/month (the same server offering with an ipv4 address costs $3.50/month). It's nice to see them offering that kind of discount, but I have no idea whether or not there's anything similar for their more powerful offerings.

  The only downside is you cannot do BGP on those IPv6-only hosts, as their BGP speaker is IPv4-only, so you cannot BYOIPv4 to those hosts, unless you route via their private network to another IPv4 enabled host first.
  - Anunayj 5y ago
    Oh, I wasn't even aware that was a thing. How does that work? Don't you have to buy blocks of IPv4 (which would be rather expensive) and then route them all the the Host. What advantage would Bringing your own IP have anyway?

      If you want some serious redundancy nothing beats running services anycast with BGP across multiple cloud providers. Also, some services, like, say, DNS servers need long-term portability of specific IPs across multiple providers. I do both, actually on Vultr.

        > If you want some serious redundancy nothing beats running services anycast with BGP across multiple cloud providers. Unless they're TCP services. Or stateful UDP services. Then you're in for a world of pain if you try to anycast them. The list of sensibly anycast services is surprisingly low. Stateless UDP services, essentially, which isn't a big list. Especially if you're the kind of person who's using Vultr's cloud, and not a megacorp. If you have the resources to develop backend state sync, you're probably still better serviced with a (set of) load balancer(s).

Vultr has v6 only servers which come at a slight discount. I think it will become more common and they can be useful for some tasks like running chat bots and stuff for APIs with v6 support.
