IPv6 deployment for websites and servers

Treat IPv6 as a real production path

Publishing an AAAA record tells compatible users to reach your service over IPv6. That path needs the same attention as IPv4: correct routing, service bindings, firewall policy, TLS, logs, and monitoring. It should not be enabled as an untested checkbox.

IPv6 allocation and routing depend on the HostGanga product and location. Confirm support for the chosen plan before designing around it, especially when you need a particular prefix model or reverse DNS.

Controlled dual stack

Run IPv4 and IPv6 together while clients transition, and test each path independently.

Explicit IPv6 policy

Create firewall rules for IPv6 rather than assuming the IPv4 policy automatically applies.

Application readiness

Check listen addresses, trusted-proxy settings, logs, rate limits, and access-control parsing.

Deploy in a measurable sequence

Confirm the address and route, bind the service, apply inbound and outbound policy, and test directly before publishing DNS. Add the AAAA record only when HTTP, TLS, application behavior, and monitoring work from an external IPv6 network.

• Avoid broad inbound rules for an entire prefix
• Monitor IPv4 and IPv6 endpoints separately
• Keep AAAA and A records pointed at equivalent service versions

Audit assumptions in software

Older scripts may expect dotted IPv4 strings, while allowlists may contain only IPv4 sources. Review databases, analytics, abuse controls, webhook validation, and URL formatting. IPv6 addresses in URLs require brackets, and privacy addresses can affect simplistic identity logic.
