En Internet las rutas se anuncian como prefijos: un sistema autĂłnomo comunica a sus vecinos por BGP que puede entregar trĂĄfico para, por ejemplo, 144.122.0.0/16 (Middle East Technical University, AS1967). Esta herramienta busca un prefijo en nuestra copia diaria de la tabla de enrutamiento global y muestra tres cosas:
- Anuncios exactos: quĂ© AS origina exactamente ese prefijo. Varios orĂgenes (MOAS) son normales en servicios anycast y algunas redes multihomed; en otros casos, sospechosos.
- Rutas que lo cubren: anuncios menos especĂficos que lo contienen. El trĂĄfico sigue la ruta mĂĄs especĂfica; la que lo cubre importa si la mĂĄs especĂfica desaparece.
- Rutas mĂĄs especĂficas: anuncios dentro del prefijo, que pueden pertenecer a otras redes (clientes, o un secuestro).
Para cada ruta anunciada también se verifica RPKI: si una ROA autoriza su AS de origen.
La tabla es la vista del colector de rutas de APNIC. La mayor parte de la tabla global se ve igual desde cualquier lugar, pero una ruta filtrada antes del colector no aparece.
Preguntas frecuentes
¿Por qué no aparece mi /24 y sà un /16?
Sus direcciones se anuncian como parte del bloque mayor y nadie anuncia el /24 por separado. Es lo normal para la mayorĂa de clientes de un operador.
ÂżQuĂ© es un secuestro por prefijo mĂĄs especĂfico?
Alguien anuncia un prefijo mĂĄs largo dentro de su espacio de direcciones. Como los routers prefieren la ruta mĂĄs especĂfica, el trĂĄfico va hacia Ă©l. RPKI con una longitud mĂĄxima estricta invalida esos anuncios.
ÂżPuedo introducir una sola direcciĂłn?
SĂ. La herramienta muestra la ruta anunciada mĂĄs especĂfica que la contiene.
