IPv6 becomes standard for new VPS plans

Providers enable dual stack and allocate /64 by default.

In 2023 IPv6 moved from optional to standard on new VPS plans. Providers now enable dual stack and allocate /64 by default. This improves reachability across regions.

The transition is not always smooth: some applications are not IPv6 ready, and some providers limit traffic. Check load balancers, mail and panel support to avoid unexpected blocks.

For B2B systems verify external integrations and antifraud tools. Many services still rely on IPv4 and need special configuration.

IPv6 reduces dependency on scarce IPv4 space and lowers address costs. Security still requires careful firewall and access rule design.

Audit logs and update monitoring. Without proper metrics, IPv6 traffic can remain invisible and create risk.

We added IPv6 support tags and protocol filters in the catalog to match real requirements.

If a provider offers NAT64 or IPv6-only plans, confirm compatibility and fallback scenarios. These plans are not for every workload.

When moving to IPv6, validate DNS and reverse records. Incorrect PTR entries can harm mail delivery and reputation.

Review security controls: firewalls, IDS, and DDoS rules. IPv6 policies are often outdated, creating new risks.

If some clients stay on IPv4, you need proper compatibility: dual stack, NAT64, or proxies. Confirm the provider supports the required scenario.

Enterprise networks should verify BGP support and the ability to announce their own prefixes. Without it, IPv6 adoption can be limited.

If your app logs IPs, ensure the format is supported and does not break analytics. A common issue is improper parsing of IPv6 addresses.

Do not skip team training and documentation. Clear runbooks for IPv6 setup and common pitfalls save hours during migration.

Add synthetic checks from IPv6-only networks to detect regressions early. This catches issues that do not appear in dual stack monitoring.

Ask whether IPv6 has its own SLA and incident metrics. Without it, IPv6 problems can be ignored.

Ask for IPv6 firewall templates and example configs. They speed up rollout.
