Description

Version
All

Platform
All platforms except Linux-like ones; Android, Linux, and Fuschia.

Description
IPv6 requires scope ids. These are closely related to interfaces. Mostly synonymous.

The API for setting the interface for a connection, set_interface is unavailable on some platforms.

This makes link-local ipv6 addresses almost unusable on those platforms.

Research direction

Start by tracing the set_interface API and the platform-specific connection code that handles IPv6 scope IDs. Compare the supported behavior on Linux-like and other platforms, then identify how link-local addresses are represented and tested. Done means link-local IPv6 connections work on the listed non-Linux-like platforms, with coverage for the affected cases.
