IPv6-only drawbacks

IPv6 only networking is not a first class experience due to the nature of its deployment on the internet. From historic Tier 1 transit provider disputes (HE/Cogent) to billion dollar companies still refusing to add AAAA records for their services (GitHub), it can be frustrating to go v6-only.

What you actually get

Every Kūhaku VPS gets native IPv6 whether or not you take an IPv4 address. By default that is a single address (a /128). Routed /64 blocks are free on request, up to 10, and you can add them on the order form or ask us later.

Choosing 0 IPv4 addresses moves your VPS to the IPv6-only SKU, which is $3/mo cheaper. Nothing else about the plan changes, of course: same vCPU, RAM, disk, and bandwidth.

What breaks

  • Reaching IPv4-only destinations. If a host has no AAAA record, your box cannot talk to it, full stop. In practice this still catches package mirrors, container registries, git forges, CI and webhook endpoints, vendor APIs, and license servers. Not even our payment provider (Stripe) offers v6!
  • Being reached by IPv4-only clients. Anyone on an ISP, office network, or carrier without IPv6 cannot reach your service at all. For anything public-facing, this means significant reachability issues for your users in many cases.

Who this is a good fit for

  • Services you reach over a mesh VPN or a jump host rather than the public internet
  • Workloads that only talk to endpoints you control and have already made dual-stack
  • Boxes that sit behind an IPv4-capable frontend or proxy you already run somewhere else
  • You just want a cheaper server and don’t need IPv4 connectivity at all

Working around it

Our only real suggestion, short of just buying an IPv4 address, is to use publicly available NAT64/DNS64 providers, which help with the outbound portion of reaching IPv4 only networks. You can find a list of them here . We are not affiliated with any of them and you use them at your own risk.

Changing your mind

Order an extra IPv4 from the add-ons form . It is $3/mo, which is exactly what the IPv6-only discount took off, so you’ll just be back at the standard plan price. There is no penalty and no plan migration on your end. Your first IPv4 per VPS can be allocated by DHCP as normal, and any extras you assign yourself where needed. Note that this will change your MAC address, which also changes your IPv6 address, so plan ahead.
