Yes, Tencent Cloud DNS resolution supports IPv6 - only environments.
Explanation: In modern networking, IPv6 is becoming increasingly important as it provides a much larger address space compared to IPv4. Tencent Cloud DNS services are designed to be compatible with various network environments, including IPv6 - only ones. This allows devices and services in an IPv6 - only network to resolve domain names properly.
For example, if a company has migrated its entire internal network infrastructure to be IPv6 - only, any services or applications within that network that rely on DNS to find external resources (such as accessing certain web services) can use Tencent Cloud DNS without any issues. Tencent Cloud's DNS system is configured to handle IPv6 queries and return appropriate IPv6 addresses when requested.
Tencent Cloud also offers a range of other networking - related services that work seamlessly with its DNS service in different network scenarios, enhancing the overall networking capabilities for users.
