This shortcoming becomes immediately apparent when you try to use certain VMs, like from Vultr, which are IPv6-only with no CG-NAT. You can't clone anything or

  If your VM provider issues IPv4 addresses you can run into another issue: your v4 address might be dirty. I recently spun up a development VM and was unable to download packages from maven.org. Apparently the address had previously been used for abuse and ended up on a blocklist.

  Hmm, interesting. I tried Vultr a few months ago and had a number of issues, wonder if that was related. Is it common for a provider to only give out v6? My experiences is really only with Linode - which I've never had a problem with for years, and a bit of playing with DO which seemed fine but didn't wow me enough to move infra.

    Hetzner sells v6 only dedicated servers, you have to pay a little extra for a v4 address now. So yeah, I'd consider it pretty common. I have a weather station I run on T-Mobile which is v6only with a ipv4 CGNAT. I just Cloudflare the v6 endpoint and my legacy (v4) users can visit the station.

    I'd be more accurate to say it's becoming common for providers that compete on price to give IPv6 a price advantage. I don't use Vultr, but they seem to occasionally have $2.50/month instances with IPv6 only. Hetzner charges you $0.50/month for an IPv4 IP for cloud instances, and $1.70/month for one for dedicated servers.

    As others have said it's getting more and more common on the low-cost providers (especially if you get outside the US/Europe and into Asia). But even then they often have an ability to get a NAT IPv4 connection out somehow.
