L01-BL: Yes
Rationale
IPv6/ICMP and Babel RFC 8966 are publicly specified within the IETF rights framework for implementation and use. Code-component reuse permits modification; the constraints on republishing altered RFC prose do not prohibit implementing or using the protocol commercially.
Assessment method
Documentary classification; no new runtime, interoperability or security experiment
Source context
Primary documents, published reports and versioned source review, 2026-10-15
Outstanding qualification
Retain applicable notices and each document publication-era terms. No conformance endorsement or patent license is inferred; this answers the owner-clarified use criterion, not unrestricted alteration of official RFC text.
