Estoy haciendo algunas pruebas con mi IPv6 mediante curly ping. Por alguna razón, puedo acceder a la versión IPv6 de Google y a algunos otros sitios web, pero ni siquiera puedo acceder npmjs.coma github.com. Vea los ejemplos:
Error:

¿Por qué sucede esto?
Como se indica en los comentarios aquí, tanto los sitios web que funcionan como los que no funcionan utilizan la misma interfaz. La salida de traceroutees:
