[lacnog] Resumen de LACNOG, Vol 212, Envío 9

Vie Ago 22 20:15:59 -03 2025

Estimados,
Don Alejandro,
Buenas noches,
Yo también creo que es una excelente idea, y creo que se ha hecho un excelente trabajo.Algo similar se hace con IPv4, creo que HE lo hace, y disponer de esta información actualizadaes muy interesante para el análisis. Particularmente, me gusta mucho el detalle de la informacióny los por menores, no siendo solo un simple resumen. Sería interesante ver si se puede agregar el número promedio de prefijos anunciados por los ASN. Teniendo en cuenta que un ISP puede anuncian entre /32 y /48, es bueno saber por donde van los anuncios. Gracias por el gran aporte, 
José Gregorio Cotúa
