2023年7月6日，巴西国家电信局 (ANATEL) 在官网刊发了第7971号决议，批准了电信产品中IPv6协议合规性评估的技术要求。 该法案自公告日起生效，于2024年1月8日起强制执行。

This Act updated the requirements for IPv6 for products with WWAN, xPON, xDSL, and DOCSIS. Additionally, this standard has the following main changes:

✤ Changed the IPv6 standard RFC 2460 to the new RFC 8200 for the Mobile Service (WWAN).

✤ Formalize that for products using WWAN modules already approved by ANATEL where the entire IPv6 protocol is implement in the WWAN module (not by the host), it is possible to carry out only the IPv6 protocol verification or testing only RFC 8200 would be enough to demonstrate the host meets ANATEL IPv6 requirements. Moreover, manufacturer will need to sign a declaration informing that the IPv6 protocol is fully integrated in the module.

However, for products that the IPv6 protocol is fully or partially implemented in the host’s software/firmware (E.g., implemented in Operational System), it is required to perform all the IPv6 tests again.

Regarding the tests, the major change in the new Act compared with the actual IPv6 requirement is the replacement of the RFC 2460 standard by the RFC 8200. The other testing requirements remained the same. Below is the table with the required IPv6 standards for each technology:

Note (*): WWAN 2G and 5G NR does not need IPv6 testing.
