According to the "Notice on Accelerating the Large-Scale Deployment and Application of Internet Protocol Version 6 (IPv6)," in order to accelerate the large-scale deployment and application of IPv6... To facilitate deployment, my country has formulated a series of IPv6 application standards. Among them, GB/T 46335, "IPv

6 Support Evaluation Indicators and Methods," is a standard for... This document, formulated to guide the smooth progress of large-scale IPv6 deployment in my country, is proposed to consist of five parts.

1.Website. The purpose is to present the website's domain name resolution system, network connectivity, and website system performance under an IPv6 environment. The support evaluation metrics and methods are applicable to website systems that provide services to the public and support IPv6.

2.Mobile Internet Applications (APPs). The aim is to propose solutions for mobile internet applications (APPs) in terms of IPv6 usability, Evaluation metrics and assessments for IPv6 end-to-end usability, domain name IPv6 support, IPv6 completeness, and IPv6 usage stability. Methodology. Applicable to a comprehensive evaluation of IPv6 support in mobile internet applications.

---Part 3: IP Bearer Networks. The purpose is to propose and standardize the three aspects of IP bearer networks. network readiness, network quality, and network reliability. This section outlines evaluation metrics and methods for IPv6 support, applicable to IP networks carrying Internet application services regarding their IPv6 support. The evaluation.

4.Data Centers. The purpose is to measure the impact of data centers on network traffic, network quality, and infrastructure resources. IPv6 support status, applicable to data center operators for monitoring and evaluating IPv6 support.

5.Content Delivery Network (CDN). The aim is to propose system compatibility guidelines for Content Delivery Networks (CDNs) in an IPv6 environment. Evaluation metrics and methods for IPv6 support, including quantity, resource coverage, general performance, application acceleration performance, and stability. Used for a comprehensive evaluation of the IPv6 support of content delivery network (CDN) operators. IPv

1 Scope

GB/T 46335.4-2025 is the Chinese national standard covering measuring how far a data centre really supports IPv6 - the network, the load balancers and the security appliances, the addressing and the management plane, the customer-facing services, and the scoring that separates a token deployment from a working one. Part 4 of the series, first edition. In force from 1 February 2026. Issued on 5 October 2025, it has been in force since 1 February 2026.

This document specifies the evaluation indicators for IPv6 support in data centers and describes the corresponding evaluation methods. This document is used for evaluation of data center operators that support IPv6.
